CAUTION
Never attempt to clean the heads in a manner other than described.
Doing so will void the product warranty.
To clean the heads, use the head cleaning cassette as follows:
1.
Apply power to the drive by pressing the power switch on the system
external storage expander box, or tabletop drive unit, to the on position.
2.
Insert the head cleaning cassette (PN TLZ04-HA) into the drive.
3.
With the head cleaning cassette inserted, the drive automatically
executes head cleaning. The drive ejects the head cleaning cassette
after approximately 30 seconds if head cleaning is successful.
4.
On the card enclosed with the head cleaning cassette, record every time
you use the cassette.
Under normal conditions, the head cleaning cassette is used for about
25 cleanings. Additional cassettes are available from your Digital sales
representative or DECdirect.
If the number of cleaning cycles of a particular head cleaning cassette has
expired, the drive will signal the user by flashing both the Tape/activity
LED and the Write-Protect LED. Press the eject button to remove the
cleaning cassette because the drive will not automatically eject an expired
cleaning cartridge. No cleaning action will have occurred.
