							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.

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.

Prints do not fall nicely 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 41. 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 42.
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 41. You can disable the cutter, see Turn the automatic cutter on and off on page 42.
The cutter does not cut well
By default the printer is set to automatically cut the paper after the drying time has been completed.
However, there are some papers that cannot be cut, such as canvas or very thick paper, even when
the Form feed and cut key is pressed.
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, or the paper selected is canvas, 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 27.
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 159 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 factory default, see 
Update the firmware on page 136.
CAUTION:Transparent papers and films must be calibrated using the Image Quality
Maintenance menu, Advance > Adjust paper advance, from step four in the Recalibrating
the paper advance procedure.
Recalibrating the paper advance procedure
1.Press the Menu key to return to the main menu and 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 three. If you are dissatisfied with the recalibration,
return to the default calibration, see 
Return to default calibration on page 157.
3.If you would like to fine-tune the calibration or are using a transparent paper, press the Menu key to
return to the main menu and 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, decrease the
percentage. To correct dark banding, 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.Press the Menu key to return to the main menu and select the Image Quality Maintenance menu icon
, then Paper advance calibration > Reset paper advance.
2.Wait until the front panel displays the operation has completed successfully before pressing the
Back key to return to the main menu.

Print-quality issues
 
						

							General advice
When you have any print-quality problem:
●To achieve the best performance from your printer, use only genuine manufacturers supplies and
accessories, whose reliability and performance have been thoroughly tested to give trouble-free
performance and best-quality prints. For details of recommended papers, see 
Order paper
on page 141.
●Make sure that the paper type selected in the front panel is the same as the paper type loaded into
the printer. To check this, use the View loaded paper key on the front panel. At the same time, check
that the paper type has been calibrated. Also make sure that the paper type selected in your software
is the same as the paper type loaded into the printer.
CAUTION:If you have the wrong paper type selected, you could experience poor print
quality and incorrect colors, and perhaps even damage to the printheads.
●Check that you are using the most appropriate print-quality settings for your purposes (see Printing
on page 45). You are likely to see lower print quality if you have moved the print-quality slider to
the Speed end of the scale, or set the custom quality level to Fast.
●Check that your environmental conditions (temperature, humidity) are in the recommended range.
See 
Environmental specifications on page 206.
●Check that your ink cartridges and printheads have not passed their expiration dates: see 
Maintain
the ink cartridges on page 135.
●Avoid touching the paper while printing is in progress.
