Important Maintenance Notes
To ensure the best performance of the printer, remember these important
maintenance concepts when you service the printer.
ATTENTION
Failure to observe the guidelines below can result in damage to the
equipment.
• Do not adjust the platen gap unless the original shuttle frame assembly or
platen has been replaced with a new or rebuilt unit, or unless instructed to
do so in the troubleshooting chapter.
• Never bend or “tweak” hammer springs. Always handle the hammer
springs by the thick mounting base. The hammer springs and hammer
tips are delicate and precisely aligned.
• Use only the ribbons specified in Appendix B. Use of incorrect ribbons
can lead to ink migration problems, degraded print quality, and expensive
damage to the printer.
• Do not close the forms thickness lever too tightly. Closing the forms
thickness lever too tightly can lead to smearing, degraded print quality,
paper jams, and damage to the platen and shuttle assembly.
