Symptom

Paper jams with the sorter stapler jogging function can occur under the following conditions:

1. When ST33 (20 bin S/S) is used with Cattleya 2 (B023). NOTE: If it is used for Cattleya 1(A257/A269), this will not occur.

2. When LT (11"X8 1/2") sideways is used when making 2 or more copies of an original.

Cause

The S/S main ROM software cannot compensate for the higher copy speed of Cattleya 2. The timing of the jogger function and paper feeding does not match that of Cattleya 2.

Solution

When installing the ST33 on Cattleya 2, replace the S/S main ROM with ver "G" or newer. The ROM version of the S/S main board can be viewed with copier SP7-801-005. The last digit (for example G) indicates the ROM version. Version G can also be used for Cattleya1. The part number of this new main ROM is A8315111.

Program upgrade in mass production

The main ROM upgrade (ver G) has been applied from the first January 2001 production run for each S/S. The cut-in serial numbers are as follows: A831-17: H141130001 (see NOTE-1). A831-26: 3T60110001 (see NOTE-2). A831-55: L0551XXXXXX (see NOTE-3).

NOTE

1. "H14" is the prefix number. The 4th digit refers to the production year (1 = 2001). The

5th and 6th digits refer to the production month (13=January, 14=February, ........,

23=November, 24=December).

2. "3T6" is the prefix number. The 4th and 5th digits refer to the production month

(01=January, 02=February,........,11=November, 12=December). The 6th digit refers to the

production year (1 = 2001).

3. "L055" is the prefix number, The 5th digit refers to the production year (1 = 2001) and the 6th and 7th digits refer to the production month (01=January,

02=February,........,11=November, 12=December). Because there are currently no A831-

55 models in production, there is no cut-in S/N at the moment. Please note that although the Cattleya 2 has no Lanier model at present, there are cases in which A831-55 is used with models other than Lanier.

SYMPTOM

It was found during production line tests that in duplex copy mode, the reverse side of the copy paper may sometimes stick to the upper plate when the paper passes through the transport belt unit.

CAUSE

A charged static electricity buildup on the transport belt surface repels the reverse side of the copy paper.

SOLUTION

Temporary solution on the production line

Two anti-static brushes have been attached to the transport left stay from the first production lot (B0233880, Parts Catalogue page. 77, index 1).

Final solution on the production line

The material of the transport belt has been changed from a non-conductive to a conductive one. The part number has been changed as follows:

Remarks for machines produced before the above serial numbers:

If the old transport belt (AA040023) is replaced with the new part (AA040031) in machines before the modification, remove the two anti-static brushes from the machine. This is because the extra anti-static brushes can adversely affect copy quality in these older machines.

1. Specifications & Adjustments 1-1. Blank Margin

Definition

The blank margin at the leading edge is needed to help paper separate in the fusing unit and also assists the margin in trimming the effective image area. With the current laser copier technology, the leading edge margin must be created to prev ent paper jams (not adjustable in the field).

Specification

Leading edge: 4mm ± 2mm Trailing edge: 2mm ± 2mm (4mm ± 2mm in case of Thick 1 a nd 2 modes)* Side edge: 2mm ± 2mm (maximum 4mm when sum both left and right side).

*Note: In both the Thick Mode 1 a nd 2, t here is 4mm blank margin at the lead ing edge

(predecessor model was 2mm). This is to eliminate blurred images which may occur at the trailing edge due t o pot ential paper holding problems with the new paper transfer roller system.

1-2. Registration

Definition

The registration is determined by t he paper start timing at the registration roller an d t he laser start timing, both of which can b e adjusted by SP mode. If you make the paper start timing earlier, t he i ma ge is moved toward the trailing edge. Conversely, if you make it l at er, the image is moved toward the leading edge. Note: If the timing is ma de t oo early or too late, this can c ause a paper jam.

1-3. Magnification

Definition

The margin of error for sub-scan magnification is twice as large as that of main scan magnification. This is because sub-scan magnification is affect ed by the variations in p aper feed speed (paper feed motor), in contrast to the relatively high accuracy of the image processing unit (main scan mag.).

1-4. Banding

Definition

Lighter or darker bands appear perpe ndicular to the paper feed direction at a fixed interval. The possible causes are:

! Curves develop in the trans f er belt (areas wrapped around rollers) ! Drum with areas already exposed t o l ig ht ! Un-even development roller rotation speed

Specification

No specification is available for banding. I n addition, it is not possib le t o completely elimin at e banding with current laser printing t echnology. Please refer to the i mag e sample section for the banding level.

1-5. Jitter

Definition

Dark or light bands perpendicu lar t o the paper feed direction, as vibration in the machine is transmitted to the laser writ ing area. The Interval between bands varies, however the general location is usually fixed (e. g. 130mm from the trailing edge).

Specification

There is no specification available for jitter. It is extremely difficult to completely elim inat e this symptom with current laser printing technology. Please refer to the image sample section for the jit t e r level.

Jitter in Thick or Extra Thick paper modes

If jitter appears in Thick or Ext r a Thick paper modes at the posit ion shown in figure [A], [B] and [C], please confirm the following:

1) Jitter [A]: Approx. 360 mm from the leading edge

• Possible cause: The leading edge does not enter the fusing nip [D] smoothly, and the paper impacts on some surrounding area, causing it to feel shock.

• Check to see if the fusing entranc e area components are properly alligned, and if the area is dirty at all.

2) Jitter [B]: Approx. 75 mm from the trailing edge

• Possible cause: The shock felt by the paper when the tra il in g edge leaves the registration rollers [E].

• Try adjusting the following SP modes: SP1-801-011 (Registrati on motor speed for thick paper) SP1-801-012 (Registrati on motor speed for extra thick pap er) *Default: – 0.2, value range: –5.0 to +5.0, step 0.1

3) Jitter [C]: Approx. 135 mm from the trailing edge

• Cause: The shock felt by the paper w hen t he t r ailing edge leaves the paper feed rollers [F].

• Try adjusting the following SP modes: SP1-801-005 (Paper feeding motor speed for thick paper) SP1-801-008 (Paper feeding motor speed for extra thick paper) *Default: –2.0, value range: –5.0 to +5.0, step 0.1

1-7. Thick Paper Handling 1-7-1. Overview

Thick paper handling is one of the sales points of the Cattleya series. Thick Mode (carried over from Cattleya1) has been enhanced, and Very Thick Mode has been newly added. These modes are able to handle the vast majority of thick paper types, however in some cases fine tuning of the fusing temperature may be required. Therefore, please read the following carefully and t ake the appropriate act io ns as listed at each occasion.

1-7-2. At Installation

1. Refer to the below box and follow t he instructions if the customer in w hich the machine is about to be installed uses t he l isted t ype of paper in the most frequ ent manner.

! The following papers hav e already been tested in Jap an and it was confirmed th at

the fine tuning is NOT neede d for the 3 types of paper:

- Neusiedler Colour Copy White 250g/m2

- Neusiedler Colour Copy White 200g/m2

- Hammermille Color Copy Cover 80lb (216g/m2)

! Regarding the Fedrigo ni 200g/m2, we strongly recommend to perform the “3-4.

Fine tuning #2” at the installation.

2. If not listed, a clear exp lanation to the customer is required on the different kind of paper modes available for t hi s machine, and that they follow t his setting sequence properly.

Paper Modes

Mode: G/m2: Lb. (Bond): Feeding Speed:

Normal 64 to 105 17 to 28 245 mm/sec

OHP — — 122.5mm/sec

Thick 105 to 157 28 to 42 122.5mm/sec

Very Thick 157 to 256 42 to 68 70mm/sec

1-7-3. At First Visit After Installation (Approx. 40kD)

1. When making a first visit to the customer’s site since instal lation (It is probably 40kD since the installation for cleaning the fusing blade), check the condition of the parts listed in the following table. If their condition i s similar to the pictures shown b elow , take a necessary action that is mentione d in t he t able.

15 May, 2001 Basic Tips for Cattleya 2

Part Name Part Number Conditions Action

Oil Supply Felt A2574171 If the condition is same

or comparable to the picture on the left, replace this part.

Pre-cleaning Roller

Hot Roller AE010034 (no picture). Replace if damaged.

Cleaning Roller AE042044 Clean the part.

Hot roller blade AE 043031 Clean the part.

Scraper A2574213 Clean the part.

AE042049 Replace the roller if it is

noticeably dirtier than the one shown in the picture on the left.

3-2. With the exception of the pre-cleaning roller*, if you have the condit ion as shown in the

table above (even if one of the part s in t he t able gets dirty), reduce the fusi ng t emperature according to the followin g procedure described as “FINE TU NIG #1”. This is because in most of these cases are caused by t he over-fusing, also known as “hot offset”. *As the pre-cleaning roller becomes dirty under the normal operating, this should not be used to judge whether or not the fine-tu ned adjustment is needed.

The Standard Maintenance Program PM table in the Service M anual is designed to support a wide spectrum of customers, including copy shops (Print for Pay ) , graphic design firms, publishing companies a s well as general office environ me nt s . Alt hough this program is abl e t o satisfy the needs of most of these customers, there are some high-demand prof essionals (e.g. copy shops) who constantly require t he image quality to be t op level with the high-coverage prints they make. This tends to increase the number of service calls.

To accommodate this, we wou ld li ke to o f fer the Customized Maintenance Program, which is designed to consistently provide the high-demand customer with an image qualit y of Level B* or higher (see the table below for definiti ons). The CMP basically reduces t he maintenance interval in order to keep the mach ine in a better condition than it would be under the Standard Maintenance Program. We have carefully chosen only those parts t hat have a major effect on image quality and whose PM intervals could be reduced. This will allow for a reduction i n t he rising service costs.

Although we have specified reduced intervals for certain parts, the CMP is a guideline for field technicians. The actual time o f rep lac ement we leave to the technician's discretion.

Table: Definition of the Image quality lev e ls:

Rating Definition Level A (Ideal) The image quality is equivalent to that at installation. Level B (Excellent) Although not the same as at installation, still a very high level of image quality. Level C (Good) Some high-demand professionals (copy shops) may not be 100% satisfied. Level D (Fair) Most users would not be satisfied. Level F (Poor) Servicing required.

Note: The CMP was created based on the results of a 1.5 PM running test using 3 production

units.

2-2. Know the machine capability

We made the print samples by using 3 production units. These samples show how the mage quality will be deteriorated during 1.5PM (120kD). Please see them carefully and know the machine capability.

Note: You can see the big color shift on the print samples in the binders. These were caused

by the proto-type controller and its utility. So, please do not pay attention to the color

shift.

You can find three binders as a set. They were made under the following c onditions:

Binder Number

Thick paper

usage ratio

Maintenance

Cleaned the hot roller blade at 40kD only

#1 25%

during 120kD run, no other maintenance was performed. Cleaned the hot roller blade at 40kD only

#2 25%

during 120kD run, no other maintenance was performed. Cleaned the hot roller blade at 20kD only

#3 100%

during 60kD run, no other maintenance was performed.

The following two items are the key to maintain the print quality in high level:

Glossiness

(e.g. less streaks in paper feed direction and adequate glossiness)

2. Solid/halftone fill (e.g. less white streaks in paper feed direction, even and smooth solid/halftone fill))

We used the five ranking (see the section 1) to evaluate the glossiness and solid/halftone fill of the print samples:

2-4. Procedure

1. Get the following information:

- How the print-out w ill be used at the custo mer site (for sell, for internal distribution, for graphic d esi gn check).

- Customer’s dema nd

- Thick paper usage ratio

2. Discuss with the customer about the machine capabil it y and suggest the CMP if you think that this program is needed the cust omer based on the information above.

3. Find the SMP / CMP ta ble in the Appendix D. You can use this table whether the S M P or t he CMP will be performed.

Note: The CMP in the Appendix D is a guide line for the customer whose application is approx.

75% or higher thick paper usage ratio and h igh d emand on the image quality with the high-coverage prints they make. Although we have specified reduced intervals f or cert ain parts, the CMP is a guide line for field technicians. The actua l ti me of rep lacement we leave to the technician's discretion.

Appendix A: Test patterns

Max ID: ACC Pattern Banding: SP5-955-6 Solid 55 (K, C, M, Y, R, G, B, P) Jitter: SP5-955- 7, 1 dot 2x2, 180 Unevenness in Half tone: SP5-955-7, 1 dot 2x2, 128 Hue change (mail scan): SP5-955-6, Solid 110 (Purple, Green) Color shift (sub scan): SP4-417-8 (YMCK 16 gradation) Line alignment: SP5-955-14 Grid

Note: The test patterns for the banding, the jitter, the unevenness in the half tone,

and the color shift, enhance those symptom to make the troubleshooting easily. And, the level of the symptom is way wroth compare to the symptom on the printing under the normal operation. This is because the dither of the test images are different from the dither on the usual copy./print mode.

Appendix B: SP Modes

SP Mode Types

The SP modes of this copier are divided into the following eight groups:

Screen Name Group

Feed Paper feed/transport/fusing Drum Drum unit Process Process control Scanner Scanner unit Mode Operating mode/system Periphs Peripherals Log Logged data Special Mode Others (special mode s)

Service Program Mode tables

NOTE:

1) In the Function/[Setting] column:

• The related pop-up screen and SP7 function (if any) are in parenthesis after the function description,

• Comments are in italics.

• The “Setting” range is in brackets and the default “Setting” value is in

bold.

2) Clearing the RAM resets SP and UP values to their defaults. It does not affect the serial number and main counter value, however.

3) DFU Designer or Factory Use only. Do not change these values.

4) USM This SP is ignored unless the user selects ‘Service Mode’ in UP

mode.

5) IAJ See “Replacement and Adjustment - Copy Image Area
