Used to check the machine's total copy count. Will be displayed in the same manner as (16) above.
Actual copy count in the maintenance counter is displayed. Will be displayed in the same manner as
(16) above.
Used to reset the maintenance counter to zero after the completion of machine maintenance. This
test command must be executed after completion of machine maintenance.
1. Used to check the warmup time.
2. Used to perform the aging test according to the entered copy number. When the test command is
executed, the machine goes into the ordinary machine operating mode, and the warmup time
starts to count from 0 and increases every 2 seconds. The warmup time is indicated on the multi-
copy window. When the RPL turns on, warmup counting is stopped and the display remains as
it is. Depression of the CLEAR key, entry of a copy number, and depression of the REPEAT key
followed by the PSW begins the aging operation until the entered copy number is reached. The
paper misfeed detect functions stays active.
The aging test is carried out without using paper. The paper misfeed sensor is disabled.
Though identical to the test command 21, the warmup time is omitted and the heater throuble
detect function and paper misfeed detect function is disabled. The heater lamp does not actuate.)

Permits machine operational checks by omitting warmup time. RPL lights up immediately after the

1. Used to adjust the developer level (toner level).
2. Used to check action of rotating parts. With this test command, the main motor runs for 1
