							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.
General unsuccessful roll load issues
●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 towards
you.
●Check that all roll end plugs 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.
●When loading a roll on the T1200 series, the roll cover must remain open until the front panel
prompts you to close it.
●When loading the upper roll (the only roll on the T770), avoid inserting the paper into the cut
sheet slot.
Unsuccessful roll load
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 T1200 printer series prompts you to close the roll cover, 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.

							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.
NOTE:If the roll has become loose around the core, the printer cannot load the paper.
Unsuccessful sheet load
●Guide the sheet, especially thick papers, when the printer initially feeds the sheet.
●Ensure that the sheet is aligned with the reference line on the roll cover.
●Do not attempt to straighten the sheet during the loading process, unless instructed to by the
front-panel display.
●Do not use hand-cut sheets, which may be of irregular shapes. Use only purchased sheets.
In case of any problem, please follow the instructions given on the front-panel display.
If you would like to start the load process again, cancel the process on the front panel; the printer
ejects the sheet from the front of the printer.
Paper loading error messages
Here is a list of front-panel messages related to paper loading, with the suggested corrective action.
Front-panel message Suggested action
Close the roll cover when the paper load
is finishedClose the roll cover when the paper load is finished.
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.
Paper incorrectly loaded The paper has not been loaded correctly. Lift the blue lever, remove the paper
and lower the lever.
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 loose around core The end of the roll has become loose around the core. Tighten the paper to the
core or insert a new roll.
Paper not detected During the paper load process the printer did not detect any paper. Ensure the
paper is inserted fully and is not transparent.
Paper too big During 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 184.
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 184.
Roll cover closed during paper load

The paper type is not in the driver
To work with a paper not in the driver, you can use your paper as one of the presets already in the
driver, however, you must identify whether your paper is transparent or translucent, glossy or matte.
ENWW The paper type is not in the driver 137Paper issues
 
						

							NOTE:For glossy paper, it is important to use a glossy paper type, as matte black ink does not print
well on glossy paper.
Transparent or translucent paper
If your paper is a transparent film (for example, a transparency), select paper type Film >
Transparent/Clear film.
If your paper is a translucent paper (for example, technical paper), select paper type Technical
paper > Natural Tracing Paper, Vellum or Translucent bond.
Glossy paper
If your paper is a photo paper, use the Photo Paper category. For glossy or high-gloss paper select
paper type Photo Gloss Paper. For Semi-gloss, Satin, Pearl or Luster finishes, select paper type
Semi-gloss/Satin Paper.
To increase gamut on photo paper, select paper type HP Universal High-Gloss Photo Paper or HP
Universal Semi-Gloss Photo Paper, depending on the finish.
Matte Paper
Your paper type selection for matte paper depends on the paper’s ink absorption capacity. To select
a paper category and type, first identify if your paper is general purpose or photographic. Then select
the recommended paper types.
General-purpose paper
●For natural tracing papers, select paper type Natural Tracing Paper < 65 g/m2 or Natural
Tracing Paper > 65 g/m2, depending on the weight of the paper.
●
For thin papers (< 90 g/m
2) uncoated papers (for example plain paper or bright white paper)
select paper type Bond and Coated Paper > Plain Paper.
●
For light coated papers (< 110 g/m
2), select paper type Bond and Coated Paper > HP Coated
Paper.
●
For heavyweight coated papers (< 200 g/m
2), select paper type Bond and Coated Paper >
Heavyweight Coated Paper.
●
For cockle-free very thick coated papers (> 200 g/m
2), select paper type Bond and Coated
Paper > Super Heavyweight Coated Paper.
Photographic paper
For photographic paper, select paper type Photo Paper > Photo Matte Paper.
Black ink is easily removed when touched
This happens when your paper is incompatible with matte black ink. To use non-matte black ink,
select paper type Photo Paper > Photo Gloss Paper.
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

Troubleshooting print-quality issues on page 147.
The printer printed on the wrong paper type
If the printer prints your job before you were able to load your desired paper, you may have Any
selected for the Paper Type in the printer driver. When Any is selected the printer will print
immediately on whichever paper is loaded. Load your desired paper, see 
Paper handling on page 31,
and select your paper type specifically in the driver.
●In the Windows driver dialog: select the Paper/Quality tab, then select your paper type from
the Paper Type list.
●In the Mac OS Print dialog (T770, T1200): select the Paper/Quality panel, then select your
paper type from the Paper Type list.
●In the Mac OS X 10.5 or 10.6 PostScript Print dialog (PostScript printers): select the Paper/
Quality panel, then select your paper type from the Paper Type list.
●In the Mac OS X 10.4 PostScript Print dialog (PostScript printers): select the Image Quality
panel, then select your paper type from the Paper Type list.
NOTE:Any is the driver default.
An “on hold for paper” message (T1200 series only)
Based on a set of conditions that you can set when sending a job (see Paper mismatch action
on page 21), the printer will decide which of the loaded rolls of paper is more suitable to print the job.
If there is no roll of paper available that meets all the conditions, the printer will put the job on hold for
paper. You can manually resume the job, forcing it to print on a paper other than the one originally
specified, otherwise it will stay on hold.
Which criteria are used to decide on which roll a job will be printed?
When a user sends a job, the desired paper type can be set (in the driver or in the Embedded Web
Server). The printer will print the job on a roll of paper of the chosen paper type that is large enough
to print the drawing without clipping. If there is more than one roll on which the job could be printed
meeting all the criteria, the roll will be chosen according to your preferences. These can be set from
the printer’s front panel: see 
Roll switching options on page 21.
When is a job put on hold for paper?
If the paper mismatch action is set to Put job on hold (see Paper mismatch action on page 21), a job
is put on hold for paper in the following cases:
●The paper type that has been selected by the user is not currently loaded on the specified roll—
or on either of the rolls, if no roll has been specified.
●The paper type that has been selected by the user is loaded on the specified roll, but the
drawing is too large to fit on the roll—or on either of the rolls, if no roll has been specified.
If I load a new roll of paper, will jobs that were on hold for paper be
automatically printed?
Yes. Every time a new roll of paper is loaded, the printer will check if there are any jobs on hold for
paper that could be printed on the loaded roll.
ENWW The printer printed on the wrong paper type 139
Paper issues
 
						

							I don’t like jobs being put on hold for paper. Can I prevent it?
Yes, this can be done from the front panel: see Paper mismatch action on page 21.
I set the option “Paper mismatch action” to Print anyway, but some jobs
are still put on hold
If the Show print preview option is selected in the driver or the Embedded Web Server, jobs are put
on hold until you have checked the preview and resumed the job. Check that the Show print preview
option is not checked in the driver, and that there are no pending preview windows waiting for
confirmation to continue printing.
My job is exactly as wide as the roll of paper that is loaded on the printer,
but is put on hold for paper
Margins are managed in different ways depending on the file type:
●For HP-GL/2 and HP RTL files, by default, margins are included inside the drawing, so a 914
mm (36 in) HP-GL/2 and HP RTL file can be printed on a 914 mm (36 in) roll of paper and will
not be put on hold for paper.
●For other file formats, such as PostScript, PDF, TIFF or JPEG, the printer assumes that margins
need to be added outside the drawing (as, in many cases, these formats are used for
photographs and other images that do not include margins). This means that, to print a 914 mm
(36 in) TIFF, the printer needs to add margins, and the drawing needs 925 mm (36.4 in) of paper
to be printed; this would cause the job to be put on hold if the paper that is loaded on the printer
is only 914 mm (36 in) wide.
If you wish to print these file formats without adding extra margins outside of the drawing, the
Clip contents by margins option can be used. This option will force the margins to be set
inside of the drawing, so a 914 mm (36 in) TIFF can be printed on a 914 mm (36 in) roll of paper
without being put on hold. However, if there is no white space already included in the drawing’s
borders, some contents could be clipped because of the margins.
The roll paper will not advance
If you have pushed the printer up against a wall, the roll may be touching the wall at the rear of the
printer. Use the wall spacers to ensure a minimum distance between printer and wall. See 
The wall
spacers on page 7.
