Preventive Maintenance Daily (Approximately 15 minutes required)
•
Clean exposure frame glass and Mylar. The exposure frame glass and
Mylar should be kept meticulously clean. Dirt and resist flakes on these
surfaces will cause exposure defects.
•
Inspect Mylar for cuts and tears. Check the condition of the Mylar on
both exposure frames. The film should be clear and free of holes, creases,
and scratches. Replace the Mylar whenever necessary. Replacement
procedures are in the Service section of this manual.
•
Inspect exposure frame vacuum seals for cracks. Check the condition of
the inner and outer rubber seals on the frame glass. Cuts or nicks in the
seals could cause vacuum leaks and slow frame evacuation. Replace the
seals as necessary. Replacement procedures are in the Service section of
this manual.
Preventive Maintenance Monthly (Approximately 1 hour required)
Perform daily maintenance steps plus the following:
•
Lightly oil frame tracks. Lightly oil the upper and the lower exposure
frame tracks every month. Wet a small piece of cloth or paper towel with
a lightweight machine oil and rub it on the linear bearing surface. Keeping
the linear bearings oiled will ensure smooth and quiet operation.
•
Lubricate gas strut mounts. Apply a light coat of oil on the retaining ball
mountings for the gas struts that support the upper half of each exposure
frame.
Preventive Maintenance Semi-Annually (Approximately 2 hours required)
Perform daily and monthly maintenance steps plus the following:
•
Clean unit and power supplies. The inner cabinet and power supply areas
should be cleaned to prevent dust buildup.
•
Turn the printer off and allow the internal blowers to run through their
cool-down cycle. Disconnect the power and lock it out.
•
Open both side cabinet doors. Remove both power supply covers by
removing the two top forward screws and lift the covers up and forward.
Using a vacuum or compressed air, remove all accumulated dust and
debris from the cabinet and the power supplies.
•
Clean reflectors and lamp head safety glass. Clean the lamp reflectors
and the safety glass on the upper and lower lamp heads. Refer to the
lamp replacement procedures in the Service section of this manual for
disassembly information.
