HP p3005 Jamming at Fuser

[RHBlakeman]

Well no joy changing the fuser drive motor, gears and pendulum arm and greasing all as they went back in. Same exact problem so I'm focusing on controller and registration sensors. The one I'm working on is an M3035 - what a total POS and what a nightmare machine to do even the simplest things inside of. Starting to be super glad that HP shut down most ASPs for not buying their new junk to resell as I would have to stop accepting warranty repairs with these new junky printers they are putting out. This one is just past warranty with just 17k pages through it.

Well time to gut the front of the machine now.

[RHBlakeman]

No difference with removal of the registration and the metal cover forward of that, cleaning the sensors, putting it all back, same problem. Next I tore the fuser apart, regreased with a new sleeve and no change. I did leave the very back of the fuser off to have access to the exit sensor and about the time I saw the paper I tripped the sensor manually and it went to about 1.5" out of the fuser then failed with a second sheet started through the registration and under the toner. That rules out mechanicals and points to the controller board possibly being the problem since it reads the sensors and turns things on and off accordingly. This is not a fun printer especially with the danged ADF/scanner and stapler and fax added to it.

Don't know if this is your problem, but have you tried changing the formatter? Reason: these printers have a weakness and some of it is false paper jams and intermittent locking up. Just a thought, since you seem to have changed/tried everything else.

check gears that turn the fuser. remove them, clean the shafts and re-lubricate them. One of them is secured by a clip. Make sure that hasn't come off.

[RHBlakeman]

All the gears in the frame including the fuser drive motor and the 3 on the fuser and the fuser bushings have been replaced with new and greased with the same Uniflor 8172 that is used for the fuser film. Fuser film was replaced with new grease (even used a fuser from a functional P3005) and have disconnected formatter and run the unit by engine test button with same result. Right now the engine controller board and HVPS (which should have no effect on anything but the image development stage to transfer toner to the paper and erase/condition the drum) are the only things that have not been tested (no way to test other than replacement) and since the owner has a unit that was only making the grinding but someone took apart and couldnt get back together they have a known good engine control board and formatter. I'll be picking those parts up from them tomorrow and might just use the metal frame and swap parts to the empty frame from the trouble machine. If I use the present engine board and it comes back then I know it was the engine board. If the engine board doesnt make the problem on the empty frame then it is likely a malfunctioning sensor. I really want to figure this out as they have 40 or 50 of these POS Chinese machines so it's likely to come back and I have not found any site where anyone has posted a for-sure reason for it and a cure. HP does not address the issue on CSN, just the grinding problem which has been known for some time since the 24xx machines.

Another reason I want to figure this out is to keep HP from having a reason to sell more of their new junk. I'm sure they know the problem exists and probably a fix but they havent been forced to recall them so if people get tired of working on them they will junk them out and buy a replacement. Baloney - HP made this mess they need to come up with a repair, either the info to fix it or a service note to supply the parts and pay the labor.

The grinding on the 24xx series is sometimes caused by bad bushings on the fuser. The press roller moves, causing fuser gear movement, and that wears the gears on the gear drive. Replacing the fuser only doesn't fix the problem. Replacing the bushings, the fuser and the gears on the gear drive usually resolve the issue.

The P3005's work on the same principle so it can be all the things I've mentioned above. Additionally, they have a weakness in the formatter (I've been told that originally it was a bad chip, on some it's cold solder joints, on others a bad cap), that causes 49 errors, locking up at start-up or when going into a menu, getting stuck in sleep mode, and intermittent paper jams that cause a printer to stop in the middle of printing. Too much or not enough lubricant on the fixing units have also caused some problems.

I've not heard of any engine board problems or anything else other than above on these machines. These are one of the few HP machines I actually like and other than the formatter board issue, I've had very little problems with them.

[RHBlakeman]

I'm very familiar with all the causes of the grinding on the 24xx, P3005, M3027, M3035 and this one does not grind. The problem I'm having is very common by this thread and others I've found in searches but no one has found the cause, or at least posted the cause. I have a donor machine from the owner that they tore down trying to find the grinding (they thought it was from the large gear that engages the toner in the main gear set) then couldnt put it back together so they set it aside for parts use. I'll be working the problem machine this weekend after I do some work on a problematic Designjet 800PS at another site so hopefully I can find the problem and cure it once and for all and be able to post my findings.

FIXED!!!!

Well son-of-a-XXXXX it was as simple as a firmware upgrade - not the previous firmware upgrades but the one from March 6th 2010 that recently showed up. Version 20100306 48.121.4 loaded in place of 20070712 48.021.7 and it works like brand new out of the box including duplexing. Ran config pages right after the upgrade finished expecting the usual 13.05 with stop before the exit sensor on the fuser but nope it printed. Sceptical I ran a 10 sheet duplexed paper path test. No issues at all. Still skeptical I ran a 230 page duplexed PDF manual and absolutely zero issues. Ran another manual, no issues. So far 1500 pages printed since the firmware upgrade.

What made me think in the lines of the firmware was a story in the spring 2010 Service Edge that Liberty Parts Team puts out that I got today about bad firmware causing issues in the P401x an P451x machines. I had a P4014 here that was running and running and not putting voltage to the solenoid for tray 2, even after replacement of the dc controller and solenoid. Firmware upgrade fixed it. Okay lets see what HP has for the M3035 since I looked in mid March - bam! a brand new one with this year's date on it. Loaded and fixed. Might be one for the P3005 there as well - can't hurt to try it for those that have set their problem P3005's aside. Hope this is some insight for others.

I know why HP doesnt post this and nothing in the fix info about it - they want people to call at $75 a pop to find this out. I think HP ought to cough up some of what I'm going to charge the customer for bench labor.

He is right CONFIRMED FIRMWARE FIXED IT!!! Thanks brother!

I had the same exact issue. I replaced the fuser twice, and the electronics control module. I even replaced the formatter board!!!!!!!! SAME ISSUE! Then i said well i might as well do a firmware update. It finished the firmware, rebooted itself and the app said it was done. I test printed and SAME JAM ARRRGGG!!! I jumped on the phone to complain to a fellow tech and rebooted the printer manually and i heard the wonderful humming noise of the fuser and knew it was fixed. That beautiful humming that eventually turns into clicking and grinding isnt very pleasant (also a manu defect) but it sure is pleasant to hear it after battleing this thing for over 10 hours and 3 trips. Good luck out there. Just do the firmware and forget the rest- youll be wasting your time. If when you turn it on and it doesnt have the 1/6 2/6 3/6 and so on, your firmware is not up to date. DO THE UPDATE AND youll be perfect! on to bigger and better things!

I looked everywhere to find this Version 20100306 48.121.4. Can't find it. I have a couple of printers thta have the very same problem. Do you still have the zip file and is it possible to post it somewhere I can access it. It would be much appreciated!

Forget that version. Download the latest firmware update utilty for XP. Plug a USB cable between the ptr and pc. Install the drivers for the printer and then do the firmware upgrade. After it reboots and completes reboot it again manually and your done.

its BACK

So a few months later the problem returned. I have thing thing completely apart down to the last screw. I cannot figure this out. There is a fuser motor that isnt working at all and the paper jams. Anyone out there have a fix for this?!?!

Thanks.

Well may not be directly related to your problem, but i have serviced my share of HP's... a recurrent problem i have seen (even in brand new ones) is a failure in the fuser "transmission" by that i mean... what makes it rotate is the pressure roller... Tho i've seen a few times the pressure roller getting so polished that when the paper goes in the fuser... the pressure roller is rotating but doesnt pull the sheet it just skids on it even if just for a split second... it will give you an instant paper jam.
So basically yeah... pressure gets too polished... and the lubrication on the fuser film dries out... (I've seen this happen on practically new machines)
Relubricate the film (if you have the proper grease)... and next time you come across a hairy one... that jams every now and then... use a really thin sand paper... and just gently pass it across the pressure roller removing that "shinny" look, and a rub of alchool to remove any grease... that will give it that extra knack of traction to make the sheet go across it without a hitch

Re: HP p3005 Jamming at Fuser

I had the same exact problem. Remove the fuser assembly and lubricate the idler arm assembly located at the top left WITH SILICON BASED OIL. For some reason, the grease HP uses tends to get tacky and doesn't allow the arm to swing into position enough to engage the fuser for high speed. When you reassemble, watch the fuser assembly. It should start at a lesser speed, kick into high speed, then drop back down. When you queue a print, you should notice that it turn at low speed for a couple of seconds, then when the gear engages, it goes to a higher speed for your print job. Hope this helps. It seemed to do the trick for me.

BINGO! Thank you for your post! This fixed my problem. This printer only had 4K prints on it. I lubed the swing arm assembly with what I had, which was a light weight oil. It would intermittently jam single sided but every time double sided. "not swiveling" ha ha...Thank you Very, Very Much!
