ADJUSTMENT This chapter provides explanations concerning the adjustment necessary when replacing a part. The adjustment is made by changing the parameter value set in EEPROM on the main control board. The parameter can be set by the key operation from the operator panel. This printer has three kinds of maintenance modes, and it is necessary to select one of the modes when replacing any parts.
Category Item Value Functions OP MENU MEMORY ENABLE Sets Category MEMORY MENU Enable/Disable. DISABLE Set to Disable, Category MEMORY MENU of User Menu is not displayed. ADJUST ENABLE Sets Category SYSTEM ADJUST MENU Enable/Disable. DISABLE Set to Disable, Category SYSTEM ADJUST MENU of User Menu is not displayed.

Category Item Value Functions EMULATE ENABLE Changes the default PDL for each brand. PDLs that are disabled in this DISABLE menu will not be displayed at EMULATE of User Menu or OP MENU of Admin Menu. (No specific to PCL XL is provided; thus, when DISABLE IBM PPR ENABLE is set, there is not visual change.)
3.1.3 EEPROM Initial Setting Range for Events As for initialization of EEPROM, ranges differ the whole phenomenon. "O" is initialized. "–" is not initialized.

APPENDIX F MULTI PURPOSE FEEDER MAINTENANCE OUTLINE Functions This Multi-Purpose Feeder is installed on the front section of the printer, and it supplies paper automatically through the operation of pulse motor, which is driven by signals sent from the printer. The main functions are the followings: •...
MECHANISM DESCRIPTION General Mechanism The Multi-Purpose Feeder feeds the envelopes and paper into the printer by receiving the signal from the printer, which drives the pulse motor inside the Multi-Purpose Feeder, and this motion is transmitted to rotate roller-A and B. The envelope or paper is delivered from the separator into the printer. Once delivered into the printer, the envelope or paper is then controlled and fed through by pulse motor (registration) of the printer.
