[1] PRODUCT OUTLINE

This inserter is an optional unit for the AR-620 series of digital complex machines. With the inserter installed, blank sheets or printed sheets can be inserted as covers (made of cardboard) or tabbed sheets without being subject to the printing process (and without passing through a fixing unit). When the inserter is combined with a finisher (optional) and a punch unit (optional), printed sheets can proceed to the hole punching or stapling process without being subject to the copying process (or without passing through the main unit).

B. Error detection

(1) EEPROM errors

Explanation:

1) Timeout error The EEPROM is being programmed even after a predetermined

time period (150 msec) has passed.

2) Writing error The written data does not match the read data even when writing

and reading are retried.

3) Reading error Checking pieces of data read from three sources results in mis-

match even when checking is retried.

AR-CF2 OPERATIONAL DESCRIPTION 4 - 6

(2) Reverse sensor adjustment error

Explanation:

1) When the DA output exceeds the upper limit Even when the DA output is increased, the AD input value does

not fall within the appropriated range.

2) When the DA output is less than the lower limit Even when the DA output is decreased, the AD input value does

not fall within the appropriated range.

C. Alarm detection

Explanation: An alarm is issued because the size of a sheet in the tray cannot be

correctly detected when both the sub tray pullout detection sensor and the sub tray retraction detection sensor are turned OFF.

Indication: Shown by a LED on the operator panel of the inserter or of the main

unit as an inserter alarm.
