Maintaining print quality
Overview
The ColorgrafX X2 inkjet printer is a self-maintaining printer. That is,
it requires no routine maintenance. The procedures in this sections
cover head maintenance for optimum performance, maximum
resolution, and sharp details.
Head Maintenance
Normal maintenance
The printer has, at the print head home position, a vacuum pump
positioned over the print head. During the purging process, the
vacuum pump forcibly pulls ink through the print head nozzles,
removing any debris or dry ink particles. The waste ink from this
process is gathered and sent to the waste ink bottle.
After completing the print head purging process, any remaining ink
on the surface of the print head is removed by an automatic wiper.
Manual maintenance process
The printer performs automatic head cleaning during routine use.
However, when a void occurs, the trouble can be corrected using the
following head cleaning procedure:
Procedures
1. If a void occurs, print out the same image again. The automatic
head cleaning operation occurs before each print operation, thus
forcing an extra head cleaning cycle.
2. If the print still has voids, select HEAD MAINTENANCE>
NORMAL PURGING commands on the printer’s operation panel.

3. Each time the HEAD MAINTENANCE command is executed, the
printer’s inking system is purged of a small amount of ink.
4. Print the image once again.
5. If the print still shows voids, return to the HEAD MAINTENANCE
option; however, select STRONG PURGING.
6. Call your service representative if you cannot correct the print
quality.
