Printer Self-Maintenance
To maintain peak operation, reliability and print quality, the printer
has several automatic or semiautomatic maintenance functions.
(Refer to Figure 1-32.) These functions may be started automatically
after a certain number of prints or during printer startup, or they
may be started by the customer if a print quality defect is noted.
• Printhead maintenance cycle
• Paper preheater cleaning
• Transfix roller oiling
• Drum cleaning (chase page)
Printhead Maintenance Cycle
This topic describes the cleaning cycles used to remove bubbles or
foreign matter that cause a printhead jet to malfunction. Three basic
actions take place during a cleaning cycle:
• purging
• wiping
• flushing
These actions are used in different combinations for three different
types of cleaning cycles:
• quick wipe
• short cleaning
• long cleaning
The long cleaning cycle is performed automatically when the Clean
Jets menu item is run a second time.
The long cleaning is described here. The short cleaning and the quick
wipe are basically subsets of the long cleaning cycle.
