1.3.7 Caution when handling the carriage encoder film
(1) Do not leave grease on the cartridge encoder film (code strip)
The presence of grease will prevent correct reading of the slit in the carriage encoder film,
thus causing an error.
If grease is found on the carriage encoder film, clean it thoroughly using alcohol.
(2) Do not bend or scratch the carriage encoder film (code strip).
If the carriage encoder film has been bent until it shows a white line or a scratch is found on
it, replace it.
(3) Stretch the leaf spring excessively when removing/fitting the carriage
encoder film (code strip).
The carriage encoder film is secured in place under tension by means of a leaf spring.
Take care. if the spring is stretched excessively in the direction of the arrow, you will not be
able to secure the cartridge encoder film correctly next time.
You will have to stretch the leaf spring, but do not do so in excess when removing or fitting
it.

1.3.8 Caution when replacing the waste ink absorber
The waste ink absorbers are designed to sop up any excess ink ejected during the cleaning
operation or during ink squirting for maintenance, in order to maintain the good printing quality of
the BJ cartridge. The volume of ink absorbed is counted and these data stored in the EEPROM on
the SPCNT board. Once the volume is judged to have reached 100%, the message "CHECK
PRINTER" (error code ##342) will be displayed, and printing will stop, in order to ensure that
the volume of ink absorbed does not exceed the allowed limit. To clear this error, you need to
replace the waste ink absorbers and reset the waste ink volume counter. Refer to page 4-23,
Action for ##342, for details on how to reset the waste ink volume counter.
