Remarks in the PERIODIC INSPECTION CHECK LIST:
*1. Main blade
If poor cleaning occurs even before the replacement number of copies are made due to the adhesion
of paper dust, etc., since the blade edge may have been damaged, replace the main blade as re-
quired. Cleaning the edge with a dry cotton can damage it, so wipe the edge lightly using a soft cloth
soaked with alcohol; be sure to check for no adhesion of cloth fibers.
*2. Recovery blade
If the edge of the recovery blade is damaged, replace the blade.
*3 Drum
Refer to paragraph 3.2.
*4 Developer material
When the developer material is replaced, be sure to check the auto-toner sensor.
*5 Teflon roller
Refer to paragraph 3.5.
*6. Rubber roller
*7. Cleaning felt roller
Refer to paragraph 3.3.
*8. Scraper
Scraper whose tip is damaged should be replaced. If you try to scrape off the toner firmly caked on the
tip forcefully, it may easily be damaged. So replace scrapers if their tip is heavily stained.
*9. Transport roller
When oiling the transport roller, after having disassembled and cleaned the roller, apply a drop of
silicone oil, and then while turning the bushing to spread the oil, insert it.
*10.Aligning roller
After disassembling the upper or lower aligning roller for cleaning, apply one drop of silicone oil to the
inside of the bushing (sliding portion of the aligning roller).
When reassembly has been accomplished, rotate the roller to facilitate the spreading of the oil.
