[Noise] MP 301 ~ Video eye witness of Odd Noise w/ Jam Codes 020 & 060

[delosangeles]

Good day to all,

I was shown by our client a video file type 3gp. I was not able to Upload the video file here, I had hopes to share the odd loud noise with everyone.

In servicing I could not replicate the issue. I did note in the SMC logged data page 1 of 9 report Jam codes 020 & 060.

That file I was able to upload.

I am hopping to create interest & curiosity for input to the Cause of the machines noise,

Kind regards to all.

Those jam codes both have to do with the paper exit sensor. Check the drive train for the exit section. If it binds before the lead edge reaches the sensor you will get J020 and if it binds while the paper is on the sensor you will get J060. It could also be the source of the noise.

maybe the noise and the jams are not related to each other, (it's a hypothesis), I see that the jams are distant in time from each other, surely a video would help, try with a link on youtube

I find most often jam code 20 is a dirty exit sensor. the sensor sits on the fuser right infront of the exhaust fan it and often builds up with dirt and debris over time. unfortunately 3 jams since november is not much of a consistency to narrow down a specific cause of the jam. I do however notice 37 J001 power on jams logged. Have you checked the mechanism that pushes on the door switches for binding/damage/faulty sensor. there is also a push switch for the right side door immediately below the scanner that i have seen cause issues in the past. On the right side door have seen the Latch pin at the front or the hooks for the latch on the door frame become damaged causing the door not to latch properly. When broken the the door can move enough for one of the switches to open while the machine is in use.

Most often noises i have heard for these are Squeaking transfer roller bushings or a cracked bushing causing a ticking but is usually a consistent noise.

There are 3 sensors in that paper path, all the same part number. AW020198. Save yourself trouble down the road, go ahead and replace all 3.

Check the side door catches, they are held in place by flimsy plastic and when rhey break the door doesn't shut fully and you get a noise due to the transfer roller gear jumping

Oh, I forgot about that. Sometimes the transfer roller plastic bushings crack too.

Good day to all,

I have since returned to service the MP 301 : Lubing the Fuser Unit exit drive shaft & Main drive Gear & shaft.

I was able to attach Before & After Photos, However the noise was not resolved.

I did note during the visit that the Noise was present at Cold Start Up while the fuser was not Driven.

I now suspect the source of the noise is caused by the Machines Main drive assembly.

I shall perform Component Output checks to help locate the source of Noise.

I want to thank everyone for your Input as it helps me address all possible Issues current & evident along with those soon to develop into constant Issues.

Everyone have a great week.

Sounds like bad drum unit.

good!...at this point, go in sp mode and run sp804-(output check) and do a free-run mode for every single part, to identify the source of noise, but how says anothertech...easyli can be the pcdu unit, on the other hand it is the weakest part of the machine, as well as the most hated by everyone here

Good day everyone,

I have returned to the clients machine & performed Component Checks:

1. The Main Motor low speed did demonstrate a slight Game Card Shuffling noise behind the Step Motor normal sound.

2. The Main Motor High speed did reveal a loud Clunking / Grinding Kind Of noise.

I believe a removal of the Main Drive Ass'y should reveal the particular cause.

Kind regards & best wishers for Everyone for your input on the Issue.

P.S. Is posting of Video files permitted in the forum?

FYI Those are not different speeds. CW refers to clockwise(Forward). CCW refers to counter clockwise(Reverse). When running it forward with the drum unit out does it still make the noise?

You will most likely find evidence of wear on the main motor gear. You may also need to check the gear box the motor mounts on. If the gear that engages the main motor shows signs of wear you may have to replace the gear or possibly the entire box. Also check if the PCU drive gear is hard to turn. If so replace the PCU as it is what has destroyed the motor.

it happened to me a month ago, I had to throw away an mpc2003 because something got grinded in the drive box, we will use it for spare parts
- try the sp804 test without pcdu inserted, and above all test the load of the motor by disassembling it and holding it in your hand, apply some load force trying to slow it down with your hands to simulate the load, and see if it starts to generate noise.
