Otherwise, select a category with high carriage position. Ensure that ink quantity and paper nish remain the
same.
After printing, colors are not saturated enough
This may happens when too little ink is used. To use more ink, select a category with more ink from the table.
Ensure that carriage position and paper nish remain the same.
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 Use Printer Settings
or Any selected for the Paper Type in the printer driver. When either of these is selected, the printer will print
immediately on whichever paper is loaded. Load your desired paper, see Paper handling on page 25, and select
your paper type specically in the driver.
● In the Windows driver dialog: select the Paper/Quality or Paper tab (depending on the driver version), then
select your paper type from the Paper Type list.
● In the macOS Print dialog: select the Paper/Quality panel, then select your paper type from the Paper Type
list.
NOTE: Use Printer Settings (Windows) or Any (macOS) is the driver default.
Automatic cut not available
Some paper types cannot be cut by the automatic cutter. When such a paper type is loaded and active, the
printer cannot switch automatically to the other roll: the active roll must rst be unloaded manually.
On hold for paper
Based on a set of conditions that you can set when sending a job (see Solve paper mismatch on page 82), 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 specied, otherwise it will stay on hold.
NOTE: When an uncuttable roll is active, every job sent to any other paper source is put on hold until you
manually unload the uncuttable roll.
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. 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 front panel: see Roll policies on page 81.
When is a job put on hold for paper?
If the paper mismatch action is set to Put job on hold (see Solve paper mismatch on page 82), 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 specied roll—or on either
of the rolls, if no roll has been specied.
● The paper type that has been selected by the user is loaded on the specied roll, but the drawing is too
large to t on the roll—or on either of the rolls, if no roll has been specied.
