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
1. Cleaning Cartridge Product Number = HP 92283K.
2. Insert the cleaning cartridge into the drive.
3. The drive automatically cleans the drive heads and ejects the cartridge after approximately 30
seconds.
4. If the cleaning cartridge ejects after only 14 seconds, the cartridge has reached the end of its useful
life. (About 25 cleaning cycles.)
5. 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.
