*2) We recommend to replace to new Printer mechanism with the Lower housing to avoid the Main frame deformation by removing a part on the
Printer mechanism without the Lower housing (These units are not established for the service part individually). However, the these procedures
should be followed in the urgent case. In this time, the disassembly procedure is different depending on the removed unit.
* Ink system unit : ASF unit, CR unit, PSB/PSE unit, Holder shaft unit, Lower housing
* PF roller/PF motor : ASF unit, CR unit, PSB/PSE unit, Lower housing
*3) Unlike the paper eject roller shaft for the Stylus C60, there is not two hooks on the paper eject roller shaft for the Stylus Photo 810/820. So, you
can remove it from the Printer mechanism. However, you cannot replace it to new one because its roller shaft is not established for service part.
