Cleaning the Mask Spring

6820 Series 80-Column Printer User Manual
The printer ribbon contains a special lubricant to ensure that the fine
dot wires inside the printhead receive adequate lubrication. Replace
the ribbon frequently to prolong the life of the printhead. The printer
requires no additional lubrication.
To change the ribbon cartridge
1 Move the printhead mechanism to an open area.
2 Squeeze the ribbon cartridge locking tabs (on the side of the
cartridge) against the ribbon cartridge.
3 Lift the ribbon cartridge to remove the ribbon from the printhead.
Make sure the ribbon does not catch or get sticky.
4 Lift the ribbon cartridge out of the printer.
Check the mask spring behind the printhead. If the mask spring
appears to be in good condition, install a new ribbon cartridge. If the
mask spring is dirty, clean it as described below.
To clean the mask spring
1 Unlatch the printhead locking tabs to release the printhead, lift
the printhead aside, then lift up the paper bail. Do not detach the
printhead unit.
Never use a sharp object to clean between the printhead and
the platen (rubber roller) or you may damage the mask spring
and printhead.
