is that a paper feed copy or cross-feed image
line show front to back

if paper feed=which is called SUB SCAN direction <-------->
stop the image on the Image Transfer Belt and inspect it. If the streaks are visible on the Image Transfer Belt, replace the Primary Transfer Roller. If the streaks are not visible on the Image Transfer Belt, replace the Secondary Transfer Roller.


run some solid single Color PG 5 test prints to isolate if developer cause
PG5 TEST PROCEDURE
1. Output each color of test print (Y/M/C/Bk) in service mode:
Change the set value from [0] to [5] in [COPIER> Test> PG> TYPE]. In order to output a test print in e.g. yellow (single color), set [1] for [COLOR Y] and [0] for [COLOR-M/COLOR-C/COLOR-K]. Then press the start key.
For Magenta, Cyan and Black, do the same thing by setting [1] for each color.
2. If white streaks appear on any of the test prints, inspect the affected developing ass'y to see any scratches on the developing cylinder surface or any foreign substances between the cylinder and the blade.
Checking Method:
Move toner between the cylinder and the blade using a sheet of OHT. If the position of the white streaks is changed, foreign substances might be the root cause.


if cross-feed/ = which is called MAIN SCAN (they look like PITCH LINES)/=streaks in the main scanning direction appeared on a light halftone image because vibrations of the ITB created
when the ITB cleaning blade contacts the ITB was transferred to the primary transfer area

Re: IR2570 CANON STRIPES

I am very pleasantly surprised by the speed of response!!
Thanks for your knowledge.
I'll prove it tomorrow.

Clarifications:
For the time being...
-The Drum unit is new.
-Primary Transfer Roller FC5-6920-020 is new.
-BLADE,transfer cleaner FC5-0368-020 is new.
-apparently the streaks are something visible on the Image Transfer Belt.All colors (Y/M/C/Bk) !!!

My question the image transfer belt can be? contacts the ITB?? contacts Primary Transfer Roller ??? I do not know!

I think these stripes are quite common in these models of copiers.
Not a rare thing.
See you!

NOTE:
Main Scan is NOT in paper feed direction/ that is called Sub Scan

see example below--This is from ITB(3200/5180 MODELS)

If u are talking about Pitch Lines> u are right
there was something a while ago on ITB adjustments for 3100/3170/ need to research

Test results of the image stop:

-These lines appear initially in the mass of toner (Y/M/C/Bk) on the drum.
-It can be seen especially in the magenta but other colors can also be.ITB.jpgM2.jpgM.jpgx 026.jpg-The drum unit is new.

-Any suggestions ?
-probable cause?

Re: IR2570 CANON STRIPES

if u receive these pitch lines from SCANS & INTERNAL PRINTS

AND the image pitch line in on the drum before Primary Transfer to Belt>
u need to look at mechanical drive/vibration may be cause/
-------------------------------------------------------------------------------------------------
if internal network prints show same look at mechanical drive/vibration may be cause/
if only from glass scans look into scanner/reader operations

I agree with you.mechanical drive/vibration may be cause but I've checked and nothing.
I will continue investigating.
You are very kind.
Thank you.

My research has ended.

RAM CLEAR DC-CONT------>same

-My conclusion is that the HDD system software is corrupt and generates patterns and incorrect images.
Why?

Re: IR2570 CANON STRIPES

don't think it's a firmware issue-------------

your issuestripes.JPG is in SUB-SCAN = that is Paper Feed direction

The transfer image to the ITB becomes displaced because of a shock occurring when the ITB cleaning blade is engaged/disengaged.
- Transfer of image to the ITB has become displaced because of a shock occurring when the secondary transfer outside roller is engaged/disengaged.

Make the following selections in service mode to make adjustments: COPIER>ADJUST>IMG-REG.
COPIER>ADJUST>IMG-REG
Use it to fine-adjust the image sub scanning direction start position.
- REG-V-Y (Y, 1st side)
- REG-V-M (M, 1st side)
- REG-V-K (K, 1st side)
- REG2-V-Y (Y, 2nd side)
- REG2-V-M (M, 2nd side)
- REG2-V-K (K, 2nd side)
<Making Adjustments>
- An increase by '1' will move the image by a single pixel (about 0.04 mm) toward the rear.
- Be sure to enter the values indicated on the service label if you have initialized the RAM on the DC controller PCB or replaced the DC controller PCB.
<Range of Adjustment>
-10 to +10 (unit: pixel) [at time of shipment: factory value] [at time of RAM initialization: 0]

Service mode: COPIER>OPTION>BODY>TBLD-TMG (level 2)
Timing of Execution of ITB Cleaning in Direct, Full Color Mode
<Settings>
0: do not delay [at time of shipment/after RAM initialization]
1: delay
<Note>
Setting it to '1' will lead to lowered productivity.

Re: IR2570 CANON STRIPES

hood.JPG??????????????????? did u -------

did u check the laser dust-blocking sheet

If the DRUM has the Streaks before ITB receives image > as u have shown> need to work back from Drum to Charging > to Laser ????

right or wrong ??


[1] Primary charging charges the surface of the photosensitive drum to an even layer of negative potential.
[2] Laser exposure forms a static image on the drum.
[3] Development turns the static image on the drum into a visible image.
[4] Primary transfer transfers the image from the drum to the ITB. (if full color, individually for Y, M, C, and K)
[5] Secondary transfer transfers the image from the ITB to paper.
[6] Separation separates paper from the ITB.
[7] Drum cleaning removes toner from the drum.
[8] ITB cleaning removes toner from the ITB.

--------------------------------------------------

[1] Using the difference in potential between the drum surface and the developing sleeve, the machine causes the toner to move to the static image of the
drum, turning it into a visible image.
[2] Using the bias voltage applied to the primary transfer roller, the machine transfers the toner from the drum to the ITB.
[3] Using the bias voltage applied to the secondary transfer outside roller, the machine transfers the toner from the ITB to the paper.
[4] Using the brush roller, the machine stirs up the toner remaining on the drum (not having moved to the ITB), thus decreasing its bond to the drum.
[5] Using the cleaning blade positioned in contact with the drum, the machine scrapes off the residual toner from the drum.
[6] Bringing the ITB cleaning blade in contact with the ITB, the machine scrapes off the toner remaining on the ITB.

Re: IR2570 CANON STRIPES

I would like to see the single color PG5 Test Prints posted for each color

PG5 = full half-tone
1) Set the copy count, paper size, and pickup mode (single-sided or double-sided).
2) Make the following selections in service mode: COPIER>TEST>PG.
3) Make the following selections: COPIER>TEST>PG>TYPE.
4) Enter the appropriate TYPE No. using the keypad, and press the OK key.
5) Select the appropriate color using COLOR-Y/M/C/K (output at 1).
6) Set the density using DENS-Y/M/C/K (valid only if TYPE=5).
7) Press the start key.


a. Transfer Fault
If a transfer fault (white spot) occurs, suspect a fault in the ITB unit or the secondary transfer outside roller.
b. Black Line
If a black line occurs, suspect a scratch in the photosensitive drum or dirt on the primary charging roller.
c. White Line
If a white line occurs, suspect a fault in the ITB unit, secondary transfer outside roller, or laser exposure system.
d. Uneven Density
If the density is uneven at specific intervals, suspect the following:
- photosensitive drum (if at 194.7 mm)
- developing cylinder (if at 37.6 mm)
e. Uneven Density
If uneven density occurs, suspect dirt on the dust-blocking glass of the laser unit or deterioration of the ITB.

Thank you very much your help is greatly appreciated !

I have cleaned the laser dust-blocking sheet---> Caution itb transfer belt!

and then I have done the following test PG5 = full half-tone:


TEST TYPE 5_K=0_Y=0_M=0_C=1
TEST TYPE 5_K-0_Y-0_M-0_C-1.jpg
TEST TYPE 5_K=0_Y=0_M=1_C=0
TEST TYPE 5_K-0_Y-0_M-1_C-0.jpg
TEST TYPE 5_K=0_Y=1_M-=0_C=0
TEST TYPE 5_K-0_Y-1_M-0_C-0.jpgThe lines are not seen but I do not think this is the only developer that works well!

TEST TYPE 5_K=1_Y=0_M=0_C=0
TEST TYPE 5_K-1_Y-0_M-0_C-0.jpg


TEST TYPE 5_K=1_Y=1_M=1_C=1
TEST TYPE 5_K-1_Y-1_M-1_C-1.jpg

I think mechanical drive / vibration may be lines cause.
This time I suspect CLUTCH ELECTROMAGNETIC CL3.
Why? Electromagnetic clutches are often a source of problems,mechanical drive / vibration.
This clutch moves all developers cylinders...

First I'm going to replace the clutch.to see if I have luck........

Re: IR2570 CANON STRIPES

i would replace the ITB UNIT
& DEV UNITS

[ppppppppp]

Re: IR2570 CANON STRIPES

i would replace the ITB UNIT
& DEV UNITS

OK!
I have not been tested
stripes.JPGbut it appears that the developers units can be
by elimination.

I think developers units must be replaced to remove this lines.
Thanks for your help
