Replacing The Imaging Unit - Tektronix Phaser 550 User Manual

Replacing the imaging unit

Replace the imaging unit when the front panel reads
Imaging Unit: replace. Refer to ÒTroubleshooting and print quality
quick referenceÓ on page 6-10 for more information on diagnosing print
quality symptoms.
The kit consists of these items:
Imaging unit
Filter
Blower/brush cleaning tool
Caution
When replacing the imaging unit, make sure that you do not
expose either the new or used unit to light for more than
45 seconds. Place the used unit in a dark closet or empty box to
protect it from the light. (When diagnosing a print quality
symptom, you may replace the imaging unit and find it was
not the solution, and then need to put the original unit back
into the printer.)
