P4014 and Troy micr streaking

[wseyller]

Have this one customer for months now has had print quality issues. Before they were using some unknown brand rebuilt micr toner. Months ago I seem to remember that streaks appeared to be caused by either the wiper blade or recovery blade in the cartridge. I recommended the troy cartridge because I figured they are the best quality.

Even with the troy carts they have the same issue with every cart. They change the toner and it will be good until part way into the life it starts streaking and even causes backgrounding even with plain paper. I still looks like the cartridge but how can every troy cart end up with issues. It is to the point were it is getting hard to convince the customer that it is not the printer after I suggested what I always assume is the best quality micr toners.

I will soon be installing a maintenance kit at 150k just so that I can say the printer is in top shape. I do know the backgrounding happens before reaching the fuser. When last there the transfer roller was soiled with dirty contact. Cleaned it the best I could with no improvement.

We use troy MICR in our two P4015 printers and I have never had a problem.
I would for sure get Troy involved, send them samples(Return cartridges for sure)
See if they have a tech support and whats up with this problem; What would cause streaking in every cartridge?
IDK Crappy Paper/Paper dust;

Re: P4014 and Troy micr streaking

it's the cartridge. I have the same issues Troy cartridges.
Other manufacturers work fine on the same machine.

We don't supply then the carts so I let them know my recommendations. Not sure on the quality of paper. It is perforated 3 checks per page. Paper dust was non existent. There was hardly any at all.

Put in an OEM transfer roller not third party. The ones in the kits are third party. Need to order the transfer roller separate. I have lots of problems with kit parts. sep pads are worthless, transfer rollers chemically break down when the drum contacts it, when it happens toner adheres to it causing streaking and it will stick to your drum leaving speckles across the drum that look like toner and is hardened on the drum from one side to the other (left to right) you clean the drum off it comes back. I blamed it on non oem toner carts, could still have some effect on it, but in any case a oem transfer roller resolved the issue. This was a tricky one to resolve.
Here is a hint: if you ever see any repitition in any of the marks or anything, there is no need to stop the paper between the fuser and the toner cart. use a ruler (in mm) to measure the distance from one mark to the next. Then look in the service manual and it will tell you what each distance is. Better if you take note to all models you work on for quick reference. I cant tell you how many people waste their time with other methods. The stop the paper before the fuser will tell you nothing if it is the transfer roller. It just says is it the fuser or not. The ruler works best. It leaves the guesswork out. I'm only here to help and for no other reason.

Some good points. I'm very familiar with what the half stop test provides whether it is drum, transfer rollers, contacts, high voltage and such. This device had factory components until I changed them and has really had this issue for a long time. And I am certain that the transfer roller I installed was aftermarket. If I have to deal with it again I may request an OEM to eliminate a possible issue there. Thanks

Re: P4014 and Troy micr streaking

Just a thought, but have you updated the firmware on the printer?

[wseyller]

I did not.

I actually fought a machine, same model, kicking my butt. As it turned out I went through three different toner carts, stopped the paper halfway, yep its the drum, sure enough the drum would have speckles and toner stuck to it. Stuck to it I said to myself ? What the heck! I cant figure that out. I would clean the drum but it would come back. I am thinking how in the world can it stick to the drum, you know melt to it. The fans must not be working? but it would tell me that in an error, either case I checked all the fans. I could not believe it was the transfer roller. Sure enough I am not sure now if it is toner that was sticking to the drum or part of the transfer roller. Because of the design it left on the drum it look like the transfer roller. The pores and all. Somehow a chemical process occurred with the surface of the drum and it melted the transfer roller to the drum. Now this occurs to this particular printer because it is not used very often. I have others out there with no problem at all. I have noticed lately that third party parts are becoming more and more not of good quality. It is becoming frustrating. The 400/4050 kits, the rubber on the rollers are on backwards. I complained to the company, their reply: I am the only one complaining.
Some tread on other kits are too aggressive and just poor quality. The rm1-0037 type. Oh and the sep pad that comes in the kits, just as well toss them, they dont work. RL1-0007 oem is what to use. Somehow with envelopes they jam, as soon as I replace them with an oem part, instantly stops. Yes of course it has a third party feed roller. I never replace one without the other due to the clearance between the two. If either one is worn the gap widens to allow either no feed or double feed. Just stuff like that drives me nuts, you expect a new part to work without any thought. Instead you are creating problems by trying to eliminate them. If you do the firmware be very patient. Dont think it is hung up or anything as you look at the screen. Just let it do its thing. It taker a long time sometimes up to about 10 minutes or so. When it is done and your patience are about to wear thin it will reboot. Then you know it will be done.
The latest firmware as of now is 4_191_1. (35862 KB) in size.
