CANAL JR TOYS & COLECIONÁVEIS : Solução Brasil aí é somente trocar lâmina de limpeza da esteira belt ,gastaria 2 dollar ao invés de comprar uma esteira belt nova e cara, de valor alto sem necessidade, reciclar é preservar natureza, americano gosta de consumir ,gastar e poluir .
Time1 king : very informative video thanks very much.
Larry Linch : What is your website where I can purchase one of these?
Thomas Johnson : Perfect Video!! Thank You!!
Bobbie Bush : Thank you for the demonstration. I have located the transfer belt and found the source of the problem. You've saved me a technician house-call. Ordering a new transfer belt now!
Scott Neuman : As all good techs, I carry everything I need to fix this machine..... LOL
Jonathan Babusi : hp laserjet 500 color m551 can not print document with many pages. it will print 1 or 2 pages then it will reprint them again.
Greg Meyer : Thanks for your help - it worked perfectly!
Scott Clayton : You can actually get away with not ordering anything and just cleaning out the plastic housing end of the transfer belt. It's not a great design, but it's a pretty good printer otherwise. You just lift off the cover and shake it out, being careful to avoid damaging the belt or the housing. It's messy, but only takes a few minutes and saves you that £150. I've done it maybe a half-dozen times between my two M551n printers. It makes it good as new until the next time it builds up again. I recommend against wearing nice clothes when you clean it.
Airton : My Hp M551 does not print large files with pictures or drawings from Illustrator or Photoshop, for example. You would know what is the cause?

You can blow out the excess toner located in the transfer belt reservoir hopper. The hopper is a waste bin that collects excess toner from the belt over time. Check the transfer belt for vent holes around reservoir.

If you're using high compressed air from a compressor do not pull the trigger full throttle as it may damage the seals on the transfer belt . Pull compressor air trigger quarter then half way to gently blow.

The HP LaserJet printer transfer belts are programmed to generate an error message reading “REPLACE TRANSFER KIT” when the page count is at or around 120,000 pages. The only way to remove that message and restore the lifecycle, up to now, has been to purchase a costly new transfer kit.

Transfer Kit Reset Device FlashIts
Flash-It™ Restores Life to HP Transfer Kits. The Flash-It Tool will set the transfer kit life to 100% and clear the “REPLACE TRANSFER KIT” message. This will allow the printer to continue to utilize the existing transfer kit far beyond the 120,000 pages. One of the added benefits of the tool,is that you can flash the lifecycle at any point.

Andrew Kleinwaks : Thanks for the tip. Emptying the hopper made a HUGE difference, but I wish you had included that process in the video.
Brent B : The pages that I print come out with streaks. I have to clean the transfer belt and transfer roller every time I want to print. They both keep getting excess toner on them. What should I do?
Pär Nordqvist : I get black parts on my copies, especially where it is blue in pictures. It looks like the printer can’t handle colors accurate. I recently bought Laserjet 500 Color M551-dn and I find it rather bad. I bought a used one. My former printer, an HP Laserjet Pro 400 Color M451-dn was much better. I have looked at this but it looked good as far as I could see. This printer is almost 10 years so I made a blunder buying it.
Chris Newman : I thank you for the video you mentioned about the toner hopper unit. On one of the HP forums they said that my print quality problem may be due to a buildup of toner on the ITB cleaning blade. How do i do that please?
Samuel West : Hey there, I followed these instructions along with your video on removing the ITB from an HP M477fdw that was having quality problems and after cleaning and reinstalling the print quality is MUCH worse, but only if I am printing something with high toner density. So I can print pages and pages of text flawlessly, but if I try to print a poster or flyer or something it looks horrible like not nearly enough toner is coming out.
I performed the "mid-way" test and found that the issue appears to be not enough toner is getting on the belt - but again this isn't an issue for text.
Any thoughts on what could have caused this? I know the ITB is very sensitive but I was wearing nitrile gloves, was careful to not touch the belt, and didn't expose to light for any more than 10 minutes or so - just long enough to clean it.
Any thoughts on where the problem is? Is it possible the belt is ruined?
Faruk Khan : If u can post a video how to clean tonner hopper.
Bob McComb : Open what vent to dump toner? I get red speckles on my prints. I am wondering if the hopper is full?
cheese head : These things leave streaks way before 140k. Open what vent to dump toner?
A : Excuse me, please, could you write, what kind of wipe can be used with "light alcohol" to clean the ITB? Can't hear clearly at 3:36...
Poppageno : what about the other model? I got a 2605bn from a friend and it leaves color stripes on the ETB and printed media.
