6. Preventive Maintenance

This chapter contains lubrication specifications. Follow these
recommendations to prevent problems and maintain optimum
performance.

Lubrication Specifications

Lubricate only when parts are replaced or as needed, not on a
scheduled basis. Use of lubricants other than those specified can
cause premature failure. Some unauthorized lubricants may
chemically attack polycarbonate parts. Use IBM no. 10 oil,
PN 1280443 (Approved equivalents: Mobil DTE27, Shell Tellus 100,
Fuchs Renolin MR30), IBM no. 23 grease (Approved equivalent
Shell Darina 1), and grease, PN 99A0394 Nyogel 744 to lubricate
appropriate areas of the machine.
Numbers in {} refer to items in Assembly 4: Carrier Transport.
Carrier Shafts
•
Apply Nye Nyogel 744 uniformly across the top portion of the
8mm {1} and 12mm carrier shafts. The grease should be
visible to the eye on the shafts, but not dripping from the
shafts. Use 0.03 to 0.06 grams for the 8mm shaft {1}. For
reference, use 0.08 to 0.16 grams for the 12 mm shaft.
•
Remove any excessive coatings or accumulations with a lint-
free cloth. When applying Nyogel 744 to the top of the 8mm
shaft, ensure that no grease contacts the encoder strip as a
carrier system stall could result during the Power-On-
Sequence or during printing.
Note: Do not let the Nyogel 744 come in contact with the pogo
pin housing. May cause machine failure.
Carrier Transport System Pulleys
•
Apply Shell Tellus #100 to the pulley bores of the top idler
pulleys {3} and tensioner {13}. The amount of oil to b used
should be visible in the pulley bore, but should not drip. For
reference, use approximately 0.003 grams per pulley.
