CHAPTER 5 SERVICE FUNCTIONS
This chapter describes the maintenance mode and other service functions, which are exclusively
designed for the purpose of checks, settings and adjustments of the machine using the keys on the
control panel*.
* Models with touch panel use also the keys of the software keypad displayed on the touch panel. Only
when a key needs to be limited to the one on the control panel or on the touch panel, this chapter describes
a key, for example, as "the Copy key on the control panel" or "the Scan key on the touch panel." If a
description says just "the 5 key," you can use either the 5 key of the numerical keypad on the control panel
or the 5 key of the software keypad on the touch panel.
5.1 MAINTENANCE MODE
In the maintenance mode, you can update memory (EEPROM: electrically erasable programmable
read-only memory) contents for optimizing the drive conditions of the head/carriage unit or the paper
feed roller and paper ejection roller in the engine unit, if those units have been replaced, or for setting
the CIS scanner area, for example. You can also customize the EEPROM according to the shipment
destination of the machine concerned. In addition, you can perform operational checks of the LCD,
control panel PCB or sensors, perform a print test, display the log information or error codes, and
modify firmware switches (WSW).
5.1.1 How to Enter the End User-accessible Maintenance Mode
Basically, the maintenance-mode functions listed in Section 5.1.3 should be accessed by service
personnel only. However, you can allow end users to access some of these under the guidance
of service personnel (e.g., by telephone).
The user-accessible functions (codes 10 to 12, 46, 52, 53, 66, 75, 76, 80, 82, 87, 88, and 91) are
shaded
in the table given in Section 5.1.3. Function code 10 accesses the firmware switches,
each of which has eight selectors. You should not allow end users to access all of those
selectors, but you can allow them to access user-accessible selectors which are shaded
in the
firmware switch tables in the "Firmware Switches (WSW)" document separately issued.
The service personnel should instruct end users to follow the procedure given below.
(1) Models without touch panel
Press the Menu, Black Start (Mono Start), and Menu keys in this order.
TIP: For models with numerical keypad, you may press the Menu, Black Start (Mono
Start), and 0 keys instead, in the same way as conventional models.
Models with touch panel
Press the Menu key on the touch panel (or the Scan and Copy keys on the control panel
simultaneously), the Black Start (Mono Start) key, and the PHOTO CAPTURE key (or
the Scan and Copy keys simultaneously) in this order.
TIP: For models with numerical keypad on the control panel, you may press the Menu key
on the touch panel (or the Scan and Copy keys on the control panel simultaneously), the
Black Start (Mono Start) key, and the 0 key on the numerical keypad instead, in the same
way as conventional models.
