ACF Recovery Procedure
ACFs with flashing attention indicator LEDs, or ACFs with continuous
attention indicator LEDs that are not flashing, use the recovery procedures
that are listed below. Perform the recovery procedure that is appropriate for
your loader’s condition.
Attention Indicator LED Flashes
If the attention indicator LED flashes, do the following:
1. Remove the cartridge from the feed position (if present).
2. Add cartridges to the magazine if the loader is in Auto or System mode.
3. Press the Enter button, select Start and press Enter to resume operation.
Further operator service is required during the recovery situation if one of the
following conditions occurs:
v A cartridge in the drive is returned to the feed position. Remove the
cartridge, select start, and press the Enter button again to resume operation.
v In Manual or System mode, an attempt is made to load the same cartridge
that was processed. If the same cartridge will be used again, remove and
reinsert it. Press the Enter switch to resume operations.
Note: A corrected problem cancels the attention indicator LED.
Attention Indicator LEDs On Continuously (Not Flashing)
1. If a FID or ATTN message appears on the display, record the code for
future reference.
2. Initiate a manual recovery attempt by pressing the Unload switch. The
recovery is successful if the attention indicator LED on the loader is turned
off. If the attention indicator LED on the loader begins flashing, perform
the procedure that is listed in “Attention Indicator LED Flashes”.
3. If the attention indicator LED on the loader remains on continuously after
you press the Unload switch three times, issue a VARY ONLINE
command. This command is issued to the operating system from the host
operator’s console. (When the subsystem presents error information, it
posts an error message.) This step must be performed from an operating
system that currently has a path access to this device.
If the attention indicator LED remains on continuously, continue with the
following steps:
v Issue a VARY OFFLINE command from the host operator’s console of
the operating system.
v Issue a VARY ONLINE command to the operating system from the host
operator’s console.
v If a FID or ATTN message appears on the operator panel, record the
code and report it to your service representative.
4. If the attention indicator LED remains on continuously after you repeat the
recovery procedure three times, call your service representative. If a FID or
