Examples of Print Quality Issues (including possible causes and solutions)

The Memjet printhead cartridge contains over 70,000 inkjet nozzles. These nozzles are divided into ten

rows; two rows of nozzles for each color channel. Due to the high number of nozzles; it is not uncommon

for some nozzles to become contaminated or clogged.

The following examples were produced using a Five Band Color Purge YKCKM.

A similar purge pattern can be performed using the Services tab within the M Series Driver properties.

Click on the “Print Demo Page” button.

Air in Printhead Nozzle Area:

Air in the printhead nozzles will show as jagged, irregular shaped lines of missing color. Lines are normally

wider than one nozzle.

Possible Solutions:

• Run “User Level Maintenance 3” from the M Series Driver’s Services tab.

• Release the Printhead, using the “Release Printhead” button. Then close printhead latch to re-

prime the system.

• Instead of powering the printer off, when not in use, leave the print engine powered-up; so it can

perform automatic maintenance routines.

• Don’t lift the print engine to an angle greater than 60º.
