SCSI and I/O 8-87
Preventative Maintenance
Regular cleaning of the tape heads is essential to maintain the reliable operation and performance of the tape
drive. This procedure in NO WAY damages or shortens the life of either the drive mechanism or the tape
heads. The recommended cleaning frequency is every 25 hours of tape pulling time. You are advised not to
wait for the Cleaning Needed signal to appear on the front panel before implementing the cleaning
procedure. By the time the indicator is present, the performance of the drive may already have been
impacted.
Head Cleaning Procedure
Cleaning Cartridge Product Number = HP 92283K.
1. Insert the cleaning cartridge into the drive.
2. The drive automatically cleans the drive heads and ejects the cartridge after approximately 30
seconds.
3. If the cleaning cartridge ejects after only 14 seconds, the cartridge has reached the end of its useful
life. (About 25 cleaning cycles.)
4. If the cycle is successful, remove the cleaning cartridge and record the use count on the label
supplied with the cartridge.

Firmware Updates
Firmware updates can be done in two ways:
1. Download new firmware files provided with the software or as patches. This method requires the
availability of a diagnostic or utility which allows for software controlled downloading of firmware.
2. Update the firmware by way of a firmware upgrade tape available as an orderable part. The part
numbers for these tapes change on each new version release and will be made available by way of
service notes.
Firmware Upgrade Tape Procedure:
• Shut down the operating system.
• Clean the drive with the cleaning cartridge.
• Insert the firmware update tape. The drive will now take over the activity and accomplish the update.
• WAIT UNTIL ALL ACTIVITY HAS FINISHED before removing the update tape from the drive.
This is approximately two to three minutes.
Cartridge Use Per Day Cleaning Interval
1 Weekly
2 or 3 Every other day

Note
There can be no activity on the SCSI bus and no interruption of power during this procedure.
Either event can cause the device to become unusable (DEAD DRIVE) and will require the
device to be replaced.
