Background

To ensure imaging quality, the V block (or carriage beam) and felt must be cleaned and oiled every six months, during maintenance.

Important: Use only silicon oil (part number 402-00172). Do not use silicon oil together with alcohol, acetone, film cleaner, etc.

Requirements

• Oil Brackets
  • Lotem Fiberheads (part number 252-08459A)
  • Lotem Quantums (part number 291A5A397)
  • ThermoFlex (part number 291A2N300B)
  • Dolev 800 (part numbers 291B4L850 and 291B4L849)
• Silicon oil (part number 402-00172)

Procedure

1. Send the carriage to middle position.
2. Open the relevant doors and panels to allow access to the V-block (or carriage beam).
3. If relevant, remove the unload tray.
4. Remove the four screws that secure the oil brackets (2 on each bracket) and remove the oil brackets.
   Note: Keep the screws, they are used again later in this procedure.
5. Dispose of the oil brackets.
   
   

   Important: i. Clean off any oil and dirt from the V-block (carriage beam). ii. Using 70% alcohol, clean the V-block (carriage beam) to ii. prevent ablation residue/dirt from being absorbed into the oil.

   
   
6. In each new oil bracket, apply 3 cc silicon oil evenly along each felt (6 cc for Dolev 800).
   Note: Platesetters have four felts, imagesetters have two.
7. After applying the oil, allow the felt to absorb the oil for 2-5 minutes.
8. Insert the oil brackets, and insert, but do not tighten, the screws that you removed in step 4.
   Note: Use Loctite^® 242 on the screws.
9. Carefully push the brackets downward to allow the felt to be lightly pressed against the V-block (or carriage beam).
   Important: Do not exert high force on the bracket.
10. Tighten the screws on the oil brackets.
11. Send the carriage along the beam at least once.
12. If relevant, install the unload tray.
13. Close all panels and doors.
