1.3 Operations

This section outlines the operation of mechanism unit, controller, and power supply of theimage scanner.

1.3.1 Mechanism operation

The image scanner consists of a carrier unit, optical unit, mechanism unit, and automaticdocument feeder (ADF) unit. The carrier unit and optical unit consists of a CCD imagesensor, lens, and lamp. The mechanism unit has a motor that actuates the carrier unit. TheADF unit feeds the paper on the chute to the stacker tray one by one.

When the scanner is turned on, the lamp lights and the carrier unit moves to the homeposition at the left of the image scanner. If the paper remains in the transfer path, the paperis ejected, the scanner unit moves to the home position , and then the image scanner awaitsa command from the host.

(1) ADF operation

When the image scanner receives an ADF read command, the ADF motor starts and abottommost document placed faced down on the chute is fed by the ADF unit. When thepaper size sensor turns on, the ADF motor stops after inching by a specified number ofpulses.

Next the carrier unit reads the white reference (White level registration; this is done byspecified interval.), then the carrier unit moves to the ADF read position at the left of theimage scanner.

Next, the ADF motor starts rotation to feed the paper. After the TOP sensor detects theedge of the paper, the scanner starts to count the motor pulses so that the scanner starts toread just from the leading edge of the paper. Then the paper is stacked on the stacker. If allof the paper on the hopper is read and stacked, the ADF motor stops and the scanner awaitsfor next command from the host.

In carrier unit and optical unit, the lamp illuminates the document, and the reflected lightfrom the document is collected by the mirrors and lens into the CCD. The CCD convertsthe light into electrical signals for image processing.

(2) Flatbed operation

When the image scanner received a flatbed read command, the carrier unit reads the whitereference, then move to the night to start reading from the specified position. When readoperation is completed, the carrier unit moves to the home position, and then the imagescanner awaits for the next command.

In carrier unit, the lamp illuminates the document, and the reflected light from the docu-ment is collected by the mirrors and a lens into the CCD. The CCD converts the light intoelectrical signals for image processing.

3.2.3 Error and Alarm Indication

The following Errors and Alarms are checked during reading or Test feed mode.

(1) Temporary error

The following table lists temporary errors generated by the scanner and displayed via theoperator panel. The operator with a minimum amount of training or experience operatingthe scanner can generally correct temporary errors.

Error Operator Panel Sensor conditionsDisplay

Miss pick Paper Jam PAPER EMPTY to OMR (3.8 inches). If OMR is not ac-tive within 6 tries, a Paper Jam error is generated. There isa pause between each retry.

Paper Jam Paper Jam OMR to TOF. OMR is made but TOF has not been madeafter turning paper feed rollers 15". The scanner will at-tempt to clear this condition automatically 3 times. Thereis a pause between each retry.

Paper Jam Paper Jam TOF sensor on and does not go off within 20.4 inches offeeding. Then Paper Jam is detected. This error is clearedby the operator by opening the ADF and removing the docu-ment.

Double Feed Double Feed Error Length of first document is measured by TOF sensor.Subsequent documents are measured by TOF sensor. Ifdocument is +/-10, 15 or 20mm of first document an erroris generated. At this time feeding stops so doc is in ejectrollers. Default for value for double feed detection is off.This error is cleared by the operator by opening the ADFand removing the document.

(2) Alarm

The following table lists hardware alarms generated by the scanner and displayed via theoperator panel. Hardware alarms will normally require field service by trained personal.

LCD display Conditions

1 Optical Alarm (F) Only generated when start command is received or when white levelor reference is checked (every 50 scans). CCD output must be aboveOptical Alarm (B) predetermined slice level when reading the white reference. Slice level

is set in F/W and compared to the read range values. The read range isapproximately pixel 120 to 4800. If CCD output does not reach slicelevel the AGC tries to adjust the output of the amplifier to exceed theslice level. If any portion of the read range is lower than slice thenOptical Alarm is generated. Can be generated by dirty optics or refer-ence, bad lamp or CCD.

2 Mechanical Alarm After power on, carrier unit is moved to home position. Home positionis determined by activation of home position sensor. Failure is deter-mined by home position sensor not active within certain number of steps.Failure can be caused by a bad sensor, motor or carrier belt.

3 Check Shipping If a mechanical alarm occurs when the total number of sheets scannedLock by ADF is less than 100, a message and Mechanical Alarm are dis-

played alternately.

4 Motorfuse Alarm Generated immediately after the fuse is blown. Fuse is common forcarrier motor and ADF motor. Fuse is soldered to controller thereforecontroller replacement is required to repair.

5 Lampfuse Alarm There two fuses one for the front one for the back lamp. Alarm is gen-erated immediately upon failure. Fuse is soldered to controller there-fore controller replacement is required to repair.

6 Memory Alarm If amount of memory can not be determined or if a memory locationwithin detected memory returns an incorrect test value, alarm is gener-ated. Only first 4Mb of memory are checked during power on diagnos-tic. Entire memory range is checked during offline test.

7 EEPROM Alarm 128 byte EEPROM is divided into two equal 64 byte halves. The sec-ond stores the opposite values of the first. If there is ever a miss-com-pare then an alarm is generated. This is a common usage in industry.(See Section 3.2.5)

8 Image Transfer AlarmThe image data exceeds the memory installed. Or, the host computercan not process data transformation. Mounting the Extended memoryor upgrading the computer may be necessary.

4.1 Outline

Section 4.2 or later gives instructions for maintenance necessary for proper and stableoperation of the image scanner.

A periodic inspection should be performed every six months or 100,000 pages whichevercomes first.

Especially, clean the ADF and carrier units thoroughly. Cleaning intervals for the ADFunit depend on the document type and paper material. Request the user to clean the ADFunit on how frequent they use and the document type read using the image scanner.

4.2 Cleaning

This section explains how to clean each unit of the image scanner. The cleaning describedby the Section 4.2.1 and 4.2.2 are recommended to be done by the user.

4.2.1 Cleaning the document cover, document holder, and scan glass.

Clean these units (Figure 4.1) as follows:

- Clean these units using dry cloths or with a small amount of neutral detergent. Avoidusing organic solvents such as paint thinner.

- Be careful not to allow ingress of water inside the image scanner.

4.2.2 Cleaning the ADF unit

The cleaning intervals for the automatic document feeder (ADF) unit are every 5,000 pagesof paper.

This cleaning interval is only a guideline. The user should schedule cleaning depending onthe document type, paper quality, and copy quality.

For proper operation of the ADFs, users are requested to clean the ADF periodically.

Clean the ADF unit (Figure 4.2) as follows:

(1) Pull the ADF lever to open the ADF unit.

(2) Using a dry cloth or with ethyl alcohol or isopropyl alcohol, clean the following parts:

4-4

- PadWipe the pad from top to bottom (in the direction of arrow). Be careful not to catch thecloth on the pick spring when cleaning.

- ADF glass (document side)Gently wipe the ADF glass. See Section 4.2.3 "Cleaning the carrier unit" for cleaningthe back side.

- Pick rollerClean the surface of rollers thoroughly. Any toner or dirt stuck on the pick roller mayaffect paper feeding.

- Feed roller and idler feed rollerClean the surface of these rollers thoroughly. Any dust stuck on the rollers may affectpaper feeding.

- Eject roller and idler eject rollerClean the rollers gently and thoroughly not to scratch or damage the surface. Any duststuck on the rollers may affect paper feeding.

- Paper guideGently wipe the paper guide.

4.2.3 Cleaning the carrier unit

Clean the carrier unit (Figures 4.3-1 to 4.3-3) as follows:

(1) Remove the ADF lever, ADF cover, document cover, upper cover, and then the ADF unit.(See Section 4.6.6 (4))

(2) Remove the document board assembly (See Section 4.6.7)

Remove all dust or dirt on the back of the document board assembly (especially under theADF unit).

(3) Remove the Front lamp (See section 4.6.8 (3)). Blow out the dust or dirt on the mirror.Since the mirror can be scratched or damaged easily, use blower brush and do not use analcohol or dry cloths to clean the mirror (see Figure 4.3-3).And also clean the Front lamp using dry cloths.


(4) Assemble the units in the reverse order of removal.

4.2.4 Cleaning the Optical unit

Remove the Optical unit as described in Section 4.6.5 (1). (But not necessary to removethe Back lamp.) Remove the black sheet from the Carrier unit. Blow out the dust or dirton the mirror by using the blower blush. And also clean the Back lamp using dry cloths.
