Magenta dots Replace GFM20From: Bill Edwards To: "Bach Lequang (Fuji)" ,...Date: 2/24/00 3:21amSubject: Frontier Bad GFM20 Samples

Specialist Staff,Attached is a sample from a Frontier 370 with a bad GFM20 PCB. Noerrors were generated by this problem. This unit has been in operationfor a couple of months on a low volume basis. The problem is a highlypixelated image with magenta dots patterning in gradated areas mid value

between highlight and shadow. Also the monitor image represented thesedots as green instead of magenta obviously in lower resolution. Theresulting index print was fine. Dropping to monotone or disablinghypertone had no effect on the problem. Once the GFM20 PCB was replacedthe problem was gone. Just an addition to the image processing odditiescollection.Bill.Those of you getting these via dial-up sorry for the long download.

Banding / missing part of the print Replace sub scan unit

Problem Description: ( be as conciseas possible )The printer would jam and slip whilepreforming the sub scan because theroller towards the solutions on thesubscan unit would intermeitantly stop.This was because the belt part#323d889734A was riding against thewall of the subscan unit..

Solution:

Replace the unit or adjust belt tracking

with the adjustment screws

Comments: ( provide as much detail aspossible, ie. data, conditions, sequence ofevents )It would apear that this is something thatwas done at the factory and not as aresult of anything done by the owner ofthe Printer.

Any paper tests came out normal.Production prints had a yellow-orange soloarization to the highlights of the prints and/or samecolor banding on one side of the print. The problem was not consistent in the area of the printthat it occurred or the amount of the print that was effected. This problem occurred beforeupgrading machine to Ver. 1.8 and afterward. Machine was originally on Ver 1.7.*Light source stabilization for the multifunction carrier is confusing for the customer. Whenyou insert the carrier it asks you to click skip to perform the test or yes to continue. Thecustomer at my install found this to be confusing unless you read the passage carefully._Result_The correction came by changing both the FMC and FMB boards. Before replacement I triedto clean the contacts of the existing FMB board with no change. I was unable to replace justthe FMB because it was hard wired to the FMC board with blue trace wire. This part musthave been from the early stock of back-up parts Tokyo supplied to us. After installation theproblem was gone and all production was okay. Both boards were returned to parts thefollowing day. No sample prints are enclosed because the customer threw the prints set asidefor me away.

If streaked unevenness is found on a print, it is suspected that it is caused by dust in the auto film carrier.

Instruct the users to take the following measures in the event of occurrence of this problem.

[Streaked unevenness patterns]

Unclear white streaks

Mixture of unclear and clear streaks (colorless or colored)

After removing dust from the opening in the film carrier pressure cover, the opening in the film mask, the

front and back sides of the diffusion plate, and the top surface of the mirror box, carry out scanner

correction at the time of pre-operational check.

[Important] Even if no dust is found in the cleaning, be sure to execute scanner correction at the time of

pre-operational check.

If scanner correction is executed at the time of pre-operational check, an operation designated as

brightness correction (shading correction) is effected. The term "brightness correction" refers to the

process of determining correction data such as would eliminate pixel-wise variations, by turning on

the light source lamp and monitoring the CCD sensor output with no film installed. If this operation

is performed, all the elements from the light source to the CCD sensor output will be corrected

uniformly, thereby removing irregularities from the light source and diffusion plate and eliminating

variations among the CCD sensor pixels. If brightness correction is made with dust deposited on the

film carrier, the CCD output for the dusty part will be subjected to unnecessary correction because

even if the dust has been removed prior to film scanning, the correction data is one which was

obtained in the presence of dust. This results in streaked unevenness on prints.

Ref. No. PP3-010 TD-99.7-FG(HB) Printed in Japan

Types of scanner correction and their descriptions

Scanner correction is roughly classified by timing and method into the following three types:

(1) At the time of pre-operational check [Required time: about 90 to 120 sec]

(2) At the time of new film carrier installation within the day of operation [Required time: about 90 to 120

sec]

The same scanner correction (brightness correction) as executed at the time of pre-operational

check is carried out.

(3) At the time of film carrier replacement (film carrier installation at the second and subsequent times)

within the day of operation [Required time: about 40 sec]

The presence of a film mask (darkness correction) and the film carrier ID are checked.

No brightness correction is made.

In the process of brightness correction, the brightness correction data obtained in the first session

are downloaded to the CDS circuit board (the circuit board in the image processing section for CCD

sensor output A/D conversion and correction).

NOTE: For film carrier installation at the second and subsequent times within the day of operation, be

sure to use the printing screen. If the film carrier is replaced using a screen other than the

printing screen, a message "Perform scanner correction in "Pre-operational check"" is

displayed when the printing screen appears and as a result, the time required for scanner

correction is elongated.

Countermeasure

Y/R fog abruptly appears on prints.

This phenomenon is also observed on adjustment check prints such as upkeep prints.

The above phenomenon is attributable to reverse insertion of the CP-48S replenisher cartridge.

We checked the empty replenisher cartridge used and found a dent at the error insertion protect notch.

This indicates that P2RB entered P1R and mixed into P1. (The user forced the cartridge into the

equipment ignoring the correct installation direction).

When the amount of replenisher mixed is small, the above abnormality cannot be observed even after

control strip processing (FA9).

As the amount of replenisher mixed increases, the abnormality (stain: skin-colored, sensitivity: Dmax)

becomes obvious.

Although an error insertion protective mechanism is provided, please instruct the users again to install the

replenisher cartridge correctly.

We are now planning to devise an effective countermeasure in consideration of the present case.

A cyan belt-like image appears on prints (regardless of print sizes) in the main optical scanning direction.

Further, the images on prints just before and following such a print are distorted.

Cyan belt-like image

Direction of travel Distorted

Pulse motor noise from the subscanning, sorting, and other sections is induced into the polygon rotation

control circuit in the laser unit of the output device, thereby giving rise to a temporary polygon rotation

error.

In order to eliminate the effect of the above noise, connect the junction cable to the "OPT1" connector on

the laser unit.

In previous cases, this phenomenon occurred in a relatively early stage of service.

If the phenomenon does not occur within the period of 10 days to 2 weeks after the start of operation, it is

therefore considered that the machine is unlikely to suffer from the above-described trouble.If this phenomenon should be observed in a machine in use in the field, immediately take the above

countermeasure to correct it.

When this phenomenon does not occur, take the countermeasure later when visiting local shops.

We are now keeping junction cables at the ready. As soon as junction cables become available, it will be

announced.

In portraits, part of the image other than in the face area is excessively

high in density. Cases have arisen in which part of the image above the

face (outward in the film feed direction) has an excessively high density.

The problem occurs in the step of image processing for change of facial expression. The processing for

altering facial expression is performed as follows: a mask image is prepared by extracting the face from

the pre-scanned image, and enlarging it to the fine-scan image size for correction.

Of the enlargement ratios for enlargement to the fine-scan image size, the one in the film feed direction

was incorrectly calculated; the mask image was over-enlarged by about 30% in the film feed direction.

Since the mask and fine-scanned images were aligned with each others center, the corrected part was

shifted outward in the film feed direction. This phenomenon occurs regardless of the type of software(Ver.2.0 and Ver.3.0 with a face expression function), AFC, MFC, and film.

The avoid the occurrence of the problem, deactivate the functions of "RP-tone Correction" and "Face

Expression" by performing the following operations.

Select Setup and Maintenance menu and select SE1 and above level for user name.

Select Print Condition Setup and Check and Image Correction Setup.

Set RP-tone Correction and Face Expression to No. RP-tone Correction and Face

Expression appear only select Color Negative Film in Input Type .

After the above setup, it isnt necessary to restart the system.

Countermeasures will be taken when introducing Ver.4.0.
