[Jamming] MP6000 ADF runs 3 or 4 sheets then goes int ADF jam.

[rbazan]

I use simulation DF free run and insert 10 sheets of paper. Erratic-maybe third or 5th sheet will come out about 3" and the machine will stop and display will instruct me to remove ADF jam.

I replaced the ADF feed roller, belt and separation roller.

What have you found (not guess) caused this problem.

Just the normal things really.

• Check for obstructions.
• Clean all the fixed DF feed rollers.
• Clean all the sensors and pits and check they come on and off via input mode.
• Search the bulletins relating to the jam code.

Then failing the basics rip the back cover off and start taking a more in-depth look (clutches, solenoids, loose belts, worn or cracked gears, knackered bushings etc etc).

Same as Cipher - a million options, what jam code does it show that on the log? Sp 5990-004

I am assuming that you are using DF free run because it is jamming during normal DF operation. Can you provide us with the jam code that you are getting during normal operation?

The customer had no toner so I couldn't run the machine in normal mode but I will check for that code on Monday.

I ran ADF input check with paper stopped in ADF Group 1 bits had all zeros, Group 2 had bit 7 and 3 on and Group 3 had bits 0 and 1 on.
With paper removed Group 1 and Group 2 bits were zero and Group 3 had bits 0 and 1 on.

I'm beginning to guess Exit sensor but I'll find out as I take apart ADF. (I already charged the customer and he still owes me $10.00!)

This is probably not the solution you are looking for, but you still need to clean the sensors on the doc feeder's input tray to eliminate the chance that the doc feeder is just detecting the size of the document incorrectly.
That bit me in the sitting muscles enough back in the day.

There is a black felt over the reg sensor that is accessed by removing the left lower guide from under df (2 screws and a collared one at the front-remove the front cover first).

Most likely cause of intermittent jam

second that seen it more than once

I couldn't find sp5990-004 but I checked SP7508-01 and gives jam at 055 haven't checked what that is yet but will look it up.

I cleaned the registration- interval- and exit sensors; now it jams with every copy when I just run the Document feeder in free run (they haven't gotten toner yet.

When the DF goes into a jam; I follow the jam removal procedure but it stays in jam, have to shut machine off and back on.
*I ran an input check and the registration sensor is showing paper there but I had removed it but after reset the registration sensor shows no paper.

I switched the exit and registration sensors and get jam but now the DF will not reset- even when I turn machine on or off.
I checked the felt in the turn guide an it is in place- when I go back I'll try to clean any dust off it- just more taking apart I guess.
I plan to order those sensors (more inventory I won't need) and try them in the DF next.
In the mean time- I disconnected the document feeder till I return.

If my info serves me correctly the above jamb code refers to original jamb history and how many ADF jambs you had on a given date.
It doesn't really give you the jamb code location of the sensor causing the problem. You would be better using sp7505-01 or there about.


If you follow what all the other guys are saying and Printout the SMC report sp5990-004 then post the first two pages to the forum;
we might be able to help you track down the problem.

Just thinking...You might need access to the "special sp mode function" to print SMC report in total. PM any of the guys and they will tell you how to elevate the service mode up one level to SP special mode. It just allows access to some extra modes nothing wonderful.

Correction, SP 5990-004.

Problem solved-I didn't see it before but replaced this sensor (SKEW CORRECTION SENSOR was dirty) to solve problem.

The manual on page 6-26 states for this sensor error: Remains off after enough time for the original to feed twice the distance from the original setting position to the skew correction sensor. (Ah; I haven't tried to figure out how to measure that yet.)

Regardless- replaced dirty skew correction sensor. Cleaned black patch (registration) in 'Entrance Scanning Guide'(This cover is not shown in service manual but is in parts manual; page 28 item 1(it is probably in User Manual to remove a paper jam.


Thanks everyone for your help.
