Preventive maintenance procedures for the Magnus 800

Important: Strictly confidential. Do not leave this document at a customer site.
Preventive maintenance (PM) must only be performed by Creo service personnel
or by trained and certified operators.


To print out the preventive maintenance instructions below, click on the print icon at the top of the page.

Note:

PM and jigs part lists:

Before going to the site:

Important:
During the PM procedures, do not dismantle any part which has not been specified for checking, cleaning or greasing.

Imaging

Recommendation:  To properly assess image quality, the processor chemistry should have been serviced and filled with fresh chemicals within the previous 24 to 48 hours.

Expose a Creo Plate Test Target (CPTT) in the client’s favorite format. This will serve as your reference plate.

Imaging

Do the following...

Reference
Imaging quality Inspect the exposed CPTT reference file.

 
Laser Check the laser graph and power as described in the Thermal 2: Planned Maintenance Procedure.
Compare the results with the results of the last PM. 		Thermal 2: Planned Maintenance Procedure
   

Safety and Exterior

Objectives:  Check safety first!  Determine that all Magnus 800 components are safe to operate and to work on. Walk around the entire device to examine the exterior and surroundings for damage and any issues that may require further investigation or repair.

Safety and Exterior Evaluation

Do the following...

Reference
Site conditions Verify that the site conditions, including humidity and temperature, are within the specifications.
Record the humidity and temperature readings on the PM report, and inform the operator if any of the conditions fail to fall within the following ranges:
  • 20°C - 30°C (68°F to 86°F)
  • 40% - 60% relative humidity (non condensing)
  • Staccato 10 maximum temperature variation allowed: ±2.5/C
 
Doors,
panels, and interlocks
  1. Visually inspect the overall condition of all surfaces.
  2. Open each door and panel.
  3. In Magnus Controller, check safety interlocks and verify that they function correctly.
 Need to link to safety guide
Debris cabinet hose Verify that the exterior hose is not impeded or broken.
 
Cooling fluid leaks
  1. Check the floor at the side of the platesetter and verify that there are no external fluid leaks.
  2. Check the fluid level. Add fluid if required.
 
   

Backup Settings

Objectives:  Determine that Magnus 800 is operating correctly. Note any irregularities for further investigation.

System Operation

Do the following...

Reference
Backup settings Back up all the parameters that are regularly stored on the workstation - by the Controller or Service Shell, and on the device iteslf by firmware such as the MCE and thermal head.
Firmware upgrade If required, update to the current controlled release version as described in the section Downloading Firmware in the Service Shell online help.
   

Assemblies and Components

Objectives:  Check everything, then go back and repair or adjust as required.
Important:  Before opening any doors and panels.

Load and unload at least three plates of different sizes. Verify that the loading and unloading sequences progress successfully.
Successful loading and unloading verifies that the lead/trailing edge clamps (LEC/TEC) and drum balance systems are working properly.
