4. PREVENTIVE MAINTENANCE (PM) 
4.1 PM Support Mode 
4.1.1 General description
The timing for the parts replacement usually depend s on the number of output pages ever printed after 
they were replaced before. However, the life span o f them changes depending on the general use of 
users and the environment in which the equipment is  placed. Therefore, it is necessary to consider not 
only the number of output pages but also the drive  counts when deciding the timing for the parts 
replacement in order to utilize the parts and mater ials effectively.
This equipment has the PM support mode, which makes  it possible to see the general use of each part 
(the number of output pages, drive counts) and repla cement record and to do a counter clearing opera-
tion more efficiently when replacing. 
The replacement record can be printed out in the li st printing mode (9S-103).

4.1.3 Work flow of parts replacement
The timing for the parts replacement usually depend
s on the number of output pages ever made after 
they were replaced before. However, its drive count s time is also to be considered when replacing the 
parts. Even if the number of output pages has reach ed the level of replacement, for instance, the part 
may still be usable with its drive counts not reachi ng the specified drive counts. On the other hand, t he 
part may need replacement even if the number of outp ut pages has not reached the level of replace-
ment with its driving time exceeding the specified d rive counts. The life span of some parts such as fee d 
roller is heavily dependent on the number of output  pages rather than the drive counts.
The following work flow diagram shows how to judge  the timing of replacement with the number of out-
put pages and the drive counts. 
Example 1:
When the number of output pages has reached the spe cified level
Example 2:
When the image failure occurred before the number of output pages has reached the specified 
level
 The parts in RADF 
 The parts in feeding system The parts in the drum/cleaner unit 
 The parts in the fuser unit
 The parts in the developer unit 
 The parts in the transfer/separation charger unit
Replace the part.
Yes
No Replace the part.Check the drive counts at PM  
support mode. 
Does it exceed the specified 
drive counts?
Replace the part after the  
drive counts has reached the  
specified count.
The part is still usable.
Check the drive counts of all parts at PM support mode.
Does it exceed the specified drive count?
Check the part and equipment according to the “TROUBLESHOOTING”. Replace the part.

e-STUDIO280/282: When the number of output pages has  reached 270,000 or 2.5 years have 
passed from the start of use (Whichever is earlier)
(1) Replace all the supplies.
(2) Check the components in the drive section (gears , pulleys, timing belts, etc.). Replace them with 
new ones if they are damaged.

[Preventive Maintenance Checklist]
Notes:   Perform cleaning and lubricating in the following  timing. Lubricate the replacement parts 
according to the replacement cycle. e-STUDIO200L/202L: every 64,000 sheets 
e-STUDIO230/232: every 74,000 sheets
e-STUDIO280/282: every 90,000 sheets
 Values under “Replacement” indicate the replacement  cycle for the e-STUDIO200L/
e-STUDIO230/e-STUDIO280 or e-STUDIO202L/e-STUDIO232 /e-STUDIO282.
 The replacement cycle of the parts in the feeding  section equals to the number of sheets fed 
from each paper source.
 Be careful not to put oil on the rollers, belts an d belt pulleys when lubricating.
