• The platen may need cleaning or replacement. Refer to the Service Manual
(P1028249) for instructions.
There are long tracks of missing print (blank vertical lines) on
several labels.
• The printhead may be dirty or damaged.
• The printhead is dirty. Clean the printhead. Refer to the Service Manual
(P1028249) for instructions.
• The printhead is damaged. Replace the printhead. Refer to the Service Manual
(P1028249) for instructions.
• The printhead has worn out. The printhead is a consumable item and will wear out
due to friction between the media and printhead. Using unapproved media may
shorten life or damage your printhead. Replace the printhead. Refer to the Service
Manual (P1028249) for instructions.
The printing does not start at the top of the receipt or misprinting of
one to three receipts.
• The printer needs to be calibrated (refer to the two-flash sequence of "Application
User Interface" on page 69).
• Reload the media. See "Loading Media" on page 40.
Media Sensing Problems
The KR203 printer default media mode is continuous. The printer will remain in this mode
until it is changed by the Windows Driver.
The KR203 printer has automatic media calibration capability for black mark media. Once
the printer is printing or feeding media, the printer continually checks and adjusts the
media sensing to accommodate for minor changes in media parameters from page to
page on a roll, and from roll to roll of media. The printer will automatically initiate a media
length calibration if the expected media length or the page to page gap distance has
exceeded the acceptable variation range when starting a print job or feeding media.
If the printer does not detect blacklines (or notches with black mark sensing) after feeding
the media the default maximum label length distance of 24 inches (610mm), then the
printer will report a media error.
Optionally, the printer can be set to do a short media calibration after loading media or
when closing the printhead with power on. The printer will then feed up to three labels
while calibrating.
