							The paper cannot be loaded successfully
●Ensure no paper is loaded.
●Ensure the paper is far enough inside the printer; you should feel the printer grab the paper.
●Do not attempt to straighten the paper during the aligning process, unless instructed to do so by
the front-panel display. The printer automatically attempts to straighten the paper.
●The paper may be crumpled, or warped, or may have irregular edges.
Unsuccessful roll load
●If the paper does not load, the leading edge of the paper may not be straight or clean, and needs
to be trimmed. Remove the initial 2 cm (1 in) from the roll and try again. This may be necessary
even with a new roll of paper.
●Ensure the roll ends are tight against the spindle ends.
●Check that the spindle is correctly inserted.
●Check that the paper is correctly loaded on the spindle, and that it loads over the roll into the printer.
●Check that all roll stops have been removed.
●Check that the paper is wound tightly on the roll.
●Do not touch the roll or paper at during the alignment process.
If the paper has not been inserted straight, the front panel displays the following instructions.
1.When prompted by the front-panel display, lift the blue lever on the left. The printer attempts to
straighten the roll.
2.When prompted by the front-panel display, lower the blue lever. The printer checks the alignment.
If the roll is aligned, the printer measures the width and you are now ready to print.
If the roll is still not aligned, the front panel displays an error and instructions.
3.When prompted by the front-panel display, lift the blue lever on the left.
4.Rewind the roll from the end of the spindle until the edge is on the blue line.
5.Press OK, on the front panel.
6.When prompted by the front-panel display, lower the lever. The printer checks the alignment. If the
roll is aligned, the printer measures the width and you are now ready to print.
If the roll is still not aligned, the front panel displays an error and instructions to start again at step
three.
If you would like to start the load process again, cancel the process on the front panel and rewind
the roll from the end of the spindle until the edge is removed from the printer.
Unsuccessful sheet load
●Guide the sheet, especially thick papers, when the printer initially feeds the sheet.
●Do not attempt to straighten the sheet during the loading process, unless instructed to by the front-
panel display. The printer automatically attempts to straighten the sheet.
●Preferably avoid using hand-cut sheets; if you need to use them, load them with the option Sheet,
without skew check.

							If the sheet is not caught by the printer, the front-panel display asks to push paper further into the printer,
and tries to feed the paper again.
If the sheet is caught by the printer but is not inserted straight, the front panel displays the following
instructions.
1.When prompted by the front-panel display, lift the blue lever on the left.
2.Adjust the sheet to align with the front and right side blue lines.
3.Once the sheet is aligned, press OK on the front panel.
4.When prompted by the front-panel display, lower the blue lever. The printer checks the alignment.
If the sheet is aligned, the printer measures the sheet and feeds it out the back into the roll feed.
You are now ready to print.
If the sheet is still not aligned, the front panel displays an error and instructions to start again.
If you would like to start the load process again, cancel the process on the front panel and the
printer ejects the sheet out the front.
Paper loading error messages
Here is a list of front-panel display messages related to paper loading, with the suggested corrective
action.
front-panel display messageSuggested action
Paper incorrectly loaded.The paper has not been loaded correctly; the edge was not aligned with the load
guide. Lift the blue lever, remove paper, and lower lever.
Paper not found.During the paper load process the printer did not detect any paper. Ensure the paper
is fully inserted.
Paper loaded with too much skew.During the paper load process the printer detected that the paper had too much
skew. Follow the instructions on the front-panel display.
Paper too small.During the load process the printer detected that the paper is too narrow or too short
to be loaded in the printer. Press the Cancel key to stop the load process. See
Functional specifications on page 157.
Paper too bigDuring the load process the printer has detected that the paper is either too wide or
too long (sheet only) to be loaded correctly. Press the Cancel key to stop the load
process. See 
Functional specifications on page 157.
Lever lifted. During the load process the blue lever was lifted. This prevents the printer from
loading the paper. Follow the instructions on the front-panel display.
The paper type is not in the driver
TIP:First check that your driver is up to date (see Update the software on page 99). The latest driver
may offer a longer list of paper types.
To work with a paper not in the driver, you can add new paper type to your driver, see To create your
own paper preset on page 36. Adding your paper type to the driver is recommended as it allows you to
store custom parameters, such as a profile, for your paper.
ENWW The paper type is not in the driver 113

							Your new paper type must be based on an existing paper category. The available categories are:
●Bond and Coated Paper: Fiber-based, thin papers with a matte surface. These papers use matte
black ink, no gloss enhancer, relatively low ink limits and high carriage position.
●Photo Paper: Photo-base, relatively thick papers with variety of finishing from matte to satin to
glossy. These papers use photo black ink and gloss enhancer, with the exception of Photo Matte
Papers, relatively high ink limits and low carriage position, with the exception of Baryte and Photo
Matte Papers. Generally they will print with the starwheels up.
●Proofing Paper: A variety of papers from matte to satin and glossy used to simulate commercial
printing with high color accuracy requirements.
●Fine Art Material: Canvas, matte and paper-base photo materials used for high-quality fine art
printing. These papers use matte black ink and no gloss enhancer, with the exception of Canvas
Satin and Pearl papers, which use photo black and gloss enhancer. They all use high carriage
position with high ink limits.
●Film: Synthetic film-base materials that generally use photo black and no gloss enhancer, with
relatively low ink limits and high carriage position.
●Backlit: Synthetic translucent materials that use photo black and no gloss enhancer with high ink
limits, high carriage position and starwheels up.
Black ink is easily removed when touched
TIP:Handle prints with care, especially when they have just emerged from the printer.
It may be that your paper is incompatible with matte black ink. To use non-matte black ink, select paper
type Photo Paper > Gloss Photo Paper.
NOTE:When you select a different paper type, the colors of your print could change visibly.
After printing, the paper has wrinkles or there is too much ink
This happens when too much ink is used. To use less ink, select a thinner category. Matte paper
categories from thinnest to thickest are:
●Plain Paper
●Coated Paper
●Heavyweight Coated Paper
●Fine Art Paper
●Super Heavyweight Coated Paper
●Thick Fine Art Paper (>250 g/m2)

							The paper has jammed
When a paper jam occurs, you normally see the Possible paper jam message in the front-panel display.
1.Power off the printer at the front panel and also switch it off at the rear.
2.Open the window.
3.Try to move the printhead carriage out of the way.
4.Lift the blue lever as far up as it will go.

							5.Carefully remove any of the jammed paper that you can lift up and out from the top of the printer.
6.Standing behind the printer, rewind the roll or pull the cut sheet from the printer. If you cannot see
the paper, return to the front of the printer and remove it from the output tray.
CAUTION:Do not move the paper sideways, as it could damage the printer.
7.Carefully remove all small pieces of paper.
8.Lower the blue lever.
116 Chapter 11   Troubleshooting paper issues ENWW

							9.Close transparent window.
10.Switch on the printer.
11.Reload the roll, or load a new sheet. See 
Load a roll into the printer on page 25 or Load a single
sheet on page 30.
NOTE:If you find that there is still some paper causing an obstruction within the printer, restart the
procedure and carefully remove all pieces of paper.
Prints do not fall neatly into the basket
●Ensure the basket is correctly installed.
●Ensure the basket is open.
●Ensure the basket not full.
●Paper often tends to curl near the end of a roll, which can cause output problems. Load a new roll,
or remove prints manually as they are completed.
The sheet stays in the printer when the print has been
completed
The printer holds the paper to allow the print to dry after printing, see Change the drying time
on page 40. If the paper is only partially ejected after the drying time, gently pull the sheet out of the
printer. If the automatic cutter is disabled, use the Form feed and cut key on the front panel, see 
Feed
and cut the paper on page 40.
The paper is cut when the print has been completed
By default the printer cuts the paper after the drying time has been completed, see Change the drying
time on page 40. You can disable the cutter, see Turn the automatic cutter on and off on page 40.
The cutter does not cut well
By default the printer is set to cut the paper automatically after the drying time has been completed.
If the cutter is turned on but not cutting correctly, check that the cutter rail is clean and clear of any
obstacles.
If the cutter is turned off, the Form feed and cut key only advances the paper. Use this key to move the
print far enough out of the front of the printer, until it is convenient to manually cut with a straight edge
or scissors.

							The roll is loose on the spindle
The roll may need to be replaced or reloaded. If your roll has a three-inch cardboard core, ensure the
core adaptors supplied with the printer have been installed, see 
Load a roll onto the spindle
on page 23.
A strip stays on the output tray and generates jams
If a small piece of paper (200 mm or smaller) has been cut, such as before (if new roll) and after a full-
bleed print or after the Form feed and cut key has been pressed, the cut strip remains in the output tray.
Only when the printer is not working, reach in the tray and remove the strip.
Recalibrate the paper advance
Accurate paper advance is important to image quality because it is part of controlling the proper
placement of dots on the paper. If the paper is not advanced the proper distance between printhead
passes, light or dark bands appear in the print and image grain may increase.
The printer is calibrated to advance correctly with all the papers appearing in the front panel. When you
select the type of loaded paper, the printer adjusts the rate at which to advance the paper while printing.
However, if you are using custom paper or not satisfied with the default calibration of your paper, you
may need to recalibrate the rate at which the paper advances. See 
Troubleshooting print-quality
issues on page 120 for steps to determine if paper advance calibration will solve your issue.
You can check the paper advance calibration status of the currently loaded paper at any time by pressing
the View loaded paper key on the front panel. The status may be one of the following.
●DEFAULT: This status appears when loading an HP paper. HP papers in the Front Panel have
been optimized by default and unless you experience image quality problems in your printed image
such as banding or graininess it is not recommended to recalibrate the paper advance.
●RECOMMENDED: This status appears when a new paper is created. The paper advance values
for this paper are inherited from the family type. In these cases it is recommended you perform a
paper advance calibration to optimize the values.
●OK: This status indicates that the loaded paper has been calibrated before. However you may need
to repeat the calibration if you experience image quality problems such as banding or graininess
in your printed image.
NOTE:Whenever you update the printer’s firmware, the paper advance calibration values are
reset to the factory default, see 
Update the firmware on page 98.

							Recalibrating the paper advance procedure
If you are using a a transparent paper type, omit the first two steps below and advance to step 3.
1.
From the front panel, select the Image Quality Maintenance menu icon 
, then Calibrate paper
advance. The printer automatically recalibrates the paper advance and prints a paper advance
calibration image.
2.Wait until the front panel displays the status screen and re-print your print.
NOTE:The recalibration procedure takes approximately three minutes. Do not worry about the
paper advance calibration image. The front-panel display shows any errors in the process.
If you are satisfied with your print continue using this calibration for your paper type. If you see
improvement in your print, continue with step 3. If you are dissatisfied with the recalibration, return
to the default calibration, see 
Return to default calibration on page 119.
3.If you would like to fine-tune the calibration or are using a transparent paper type, select the Image
Quality Maintenance menu icon 
, then Paper advance calibration > Adjust paper
advance.
4.Select the percentage of change from -100% to 100%. To correct light banding (light-colored
horizontal lines), decrease the percentage. To correct dark banding (dark-colored horizontal lines),
increase the percentage.
5.Press the OK key on the front panel, to save the value.
6.Wait until the front panel displays the status screen and re-print your print.
Return to default calibration
Returning to the default calibration sets all the corrections made by the paper advance calibration to
zero. To return to the default paper advance calibration value, you must reset the calibration.
1.
From the front panel, select the Image Quality Maintenance menu icon 
, then Paper advance
calibration > Reset paper advance
2.Wait until the front panel reports that the operation has completed successfully before pressing
the Back key to return to the main menu.
