Cleaning

SCANNER

The manufacturer’s guide recommends cleaning the scanner daily. Proper maintenance can sustain the

life of the scanner and improve the scanning process overall.

Clean the separator pad and feed roller frequently. Use a dry cloth or a cloth moistened with a small

amount of neutral detergent or isopropyl alcohol.

Never use an organic solvent, such as paint thinner. Do not allow moisture to get inside

the device during cleaning.

AUTOMATIC DOCUMENT FEEDER (ADF)

The ADF cleaning standards differ in respect with the different types of documents that are scanned. The

rule of thumb is to clean the ADF when it has read approx. 1,000 pages. For example, frequent scanning

of documents written in pencil tends to leave lead particles on the ADF resulting in slippery rollers.

Be attentive to the high temperature of the ADF's glass surface.

Document Feed Issues

The following section provides additional information on the causes and solutions for the most common

document feed issues.

A. Multiple Page Feeding

Multiple pages are being fed into the scanner rather than one page at a time.

Problem Resolution

Improper Document Preparation

Verify the documents do not contain staples, paper clips, glued binder edges, and is

within the paper weight specifications for your scanner model.

Document Composition

The chemical composition of certain documents can cause multi-feeding. Test a scan

using standard 20-pound copy paper if the chemical composition is in question.

Improper Scanner Settings

If the batch consists of varying paper sizes and / or color, verify the double feed length

and / or thickness setting is turned off. Also verify that the paper thickness setting

matches that of the documents being scanned. Change the automatic page thickness

setting accordingly (reference the Operator’s Guide for your scanner model).

Dirty Pad Assembly / Brake Roller

Clean the ADF thoroughly; pay particular attention to the pad assembly / brake roller

using either the Fujitsu Scanner Cleaning Kit or 90% isopropyl alcohol, a lint free cloth,

and Q-tips (reference the Cleaning and Maintenance Guide for your scanner model).

Worn Pad Assembly / Brake Roller

The pad assembly / brake roller is designed to serve as an abrasive to separate the

pages in the ADF. Therefore, once it reaches the end of its wear life, they will need to

be replaced (reference the Operator’s Guide for your scanner model).

Weak or Broken Pad / Brake Roller

Springs

The pad / brake roller springs apply the proper pinch pressure to feed only one page at

a time. If the springs are weak or broken, the proper pinch pressure may not be

applied causing multi-feeding to occur. Change or adjust the springs when the pad

assembly is changed (reference the Operator’s Guide for your scanner model).

Worn Pick Roller

The pick roller pulls the page into the ADF. It works in conjunction with the pad

assembly to apply the proper pinch pressure to feed only one page at a time. If the

pick roller is at the limit of its wear life, the proper pinch pressure may not be applied

causing multi-feeding to occur. Change the pick roller (user replaceable models only).

Improperly Installed Consumables

Failure to properly install the pad assembly / brake and pick rollers may cause multi-

feeding as well as other problems.

Hardware Failure Component failure (service required).
