4.3.11 Caution regarding Ink system removal, PF roller
unit removal and PF motor removal
In case that you remove or replace the Ink system (Cap unit & Pump unit),
the PF roller unit and PF motor, we recommend to replace to new Printer
mechanism with the Lower housing
This is because these parts have to be removed or replaced on the Printer
mechanism condition without the Lower housing.
If you perform the operation with the condition, the Main frame is deformed
and the printing quality may be lowered.
Adjustment after replacing the Printer mechanism
When removing or replacing the Printer mechanism with new one, the
following adjustment must be performed in the order below.
1) Drain ink counter reset
2) Gap adjustment (Bi-d adjustment)
3) Top margin adjustment
4) 1st dot position adjustment
However, in case that you perform the operation on the Printer mechanism
without the Lower housing in urgent case, the procedures from the next page
should be followed surely.
You cannot replace the Paper eject roller, the Spur gear 60, PF motor, PF
roller and ink system with new one because these parts are not established for
service part.
