5-2 Pitney Bowes DA500/DA550 Operator Guide
Preventive
Maintenance
Clean print head, cartridge, ink surfaces and covers with plain
water only. (Water works best!)
Clean all rubber rollers with isopropyl, denatured and rubbing
alcohol only.
Use of any other cleaning solvents will void all warranties.
Keep petroleum based cleaning solvents away from rubber or
plastic parts. Anything but alcohol will cause premature break-
down of the rubber compound.
The print head performs a self cleaning cycle periodically.
If print quality is unacceptable, try the following:
• Adjust the media thickness lever (page 3-15) to
see if print quality improves.
• Clean the print head cartridge: dampen a soft
cotton cloth with water and wipe the nozzles
clean.
• Install a new ink cartridge (page 2-13).
• From the Setup Menu, select 3. Purge Printhead.
The purging process clears any clogged ink on the
print nozzle. Often this returns the print quality to a
normal level. See Appendix A, Control Panel
Menus, for information on using this feature.
