HP (Hewlett-Packard) T1200 User Manual

If you are using glossy paper, try changing to a different type of glossy paper.

Align the printheads. See 

If you have measured your printed lines and find that the lengths are not sufficiently accurate for your
purposes, you can try to improve line length accuracy in the following ways.

Print on HP Matte Film, for which your printer's line length accuracy is specified. See 

Polyester film is about ten times more dimensionally stable than paper. However, using film that
is thinner or thicker than HP Matte Film will reduce line length accuracy.

Set the Print Quality slider to Quality.

Maintain the room at a steady temperature between 10 and 30°C (50 and 86°F).

Load the roll of film and let it rest for five minutes before printing.

If you are still not satisfied, try recalibrating the paper advance. See 

.

Check that the paper type you have loaded corresponds to the paper type selected in the front
panel and in your software. To check on the front panel, use the

 key  .

Check that you are printing on the correct side of the paper.

Check that you are using appropriate print-quality settings (see 

). In some

cases, you can overcome a print-quality problem merely by selecting a higher print-quality level.
For instance, if you have set the Print Quality slider to Speed, try setting it to Quality. If you
change the print-quality settings, you may wish to reprint your job at this point in case the
problem has been solved.

Go to the front panel and select the Ink menu icon 

, then Printhead information to see the

printhead alignment status. If the status is PENDING, you should align the printheads. See
