How To Clean A Inkjet Printer

Cleaning And Maintenance Of The Feed-Rollers

 
 
Rubber rejuvenator should be used on printers that struggle to feed paper.
 
WARNING: When using rubber rejuvenator wear gloves and work in a well-ventilated area, rubber rejuvenator and plastic don’t agree, so be very careful not to get it on any part of the printer that is plastic.
 
IDENTIFY THE FEED-ROLLERS
The feed-rollers are the wheel-shaped rollers that grab the paper and feed it through the printer. You can usually access them by removing the rear door. However, not all models have a rear door, so you may have to access them through the front of the printer, where the paper sits in the tray.
 
WHY CLEAN AND MAINTAIN THE FEED-ROLLERS?
When the rubber feed rollers become worn, dirty or contaminated you may experience paper jams, poor lead edge alignment, or skewed prints (prints that are uneven from side to side). Over time the feed-rollers tend to lose the traction they had when they were new. The rubber rejuvenator helps clean and restore these rollers back into working order for optimum performance



 
TECH NOTE: This step is only meant for the main set of feed-rollers on the printer. Some models have additional sets of rollers, usually on the front of the printer where the paper comes out. These rollers cannot be cleaned with rubber rejuvenator due to the volatile nature of the chemical. 
 
CLEANING AND MAINTAINING THE FEED-ROLLERS
For this step you will need (1) foam swab from the kit, (2) are provided for this procedure and the bottle of rubber rejuvenator. First, make sure you are in a well-ventilated area away from any open flame or heat source. Apply a couple of drops of rubber rejuvenator to the foam swab or rag. Then apply this to the feed-rollers in the rear of the printer, or through the front of the printer depending on your model. Sometimes you can turn the rubber wheels by hand, but be careful not to get any rubber rejuvenator on any other part of the printer. This can cause serious damage to the printer because the rubber rejuvenator can damage the plastic in the printer. Make sure to turn the feed-rollers in the same direction as they would turn when feeding paper through the printer. (LET AIR DRY) before repeating this procedure as necessary until the whole surface of each feed-roller is covered.

 
NOTE:Be sure to let rollers air dry before using the printer.
 
TECH NOTE: Sometimes, if the printer has trouble, such as pulling multiple sheets of paper, you may have a dirty or worn separation pad. Most printers have one rubber or cork pad, usually rectangular shaped that is often located directly below one of the feed-roller tires. Sometimes the separation pad is on the paper tray, and sometimes it is located inside the machine. To clean it, apply a small amount of rubber rejuvenator on the foam swab and apply to the separation pad. This will clean it and restore traction, helping the paper feed one at a time through the printer.
 

   

 Cleaning and lubricating of the platen shaft
 
IDENTIFY THE PLATEN SHAFT (CARRIAGE ASSEMBLY SHAFT)
The carriage assembly shaft, or the platen shaft, will run the length of the printer and be located behind the carriage assembly; the round metal bar should be easy to identify.
 
WHY CLEAN AND LUBRICATE ?
The platen shaft is what stabilizes the ink carriage assembly
as it moves from side to side in the printer during the print cycle.
When the printer was produced the manufacturer used lubricant
on the shaft. This lubricant serves as a cushion between the carriage
assembly and the platen shaft. Over time this lubricant wears off and
the carriage assembly will start sticking, causing the carriage drive
belt and motor to wear. Inevitably, this will cause noise and chattering problems.

 
CLEANING
Begin by removing (1) alcohol wet wipe to clean the platen shaft
Rub the platen shaft from side to side, this will remove built up ink and debris.
Also, be sure to clean the back side.
 
LUBRICATING
Begin by opening the oil bottle
Put a few drops of oil on the swab, or rag rub it onto the platen shaft front and back and on both sides of the carriage assembly. At this point you can move the carriage assembly with your hand back and forth to work the oil into the bushings of the carriage assembly.

TECH TIP:It is recommended that you clean and lubricate the platen
 shaft periodically. This will help extend the life of the printer. 

NOTE:Do not over oil the platen shaft or drip oil into the printer.
The oil container provided has an orifice-reducer to control drops.
NOTE:The platen shaft may be difficult to reach on some models.
NOTE:The oil provided is of synthetic quality, which is the same as the


The Photo Below shows the encoder strip:
All inkjet printers have these and it is good maintenance to clean these periodically
note: when cleaning use windex just simply wipe the length of the encoder strip and be gentle
encoder strips can break easily.
