HP M605 faded (vertical) streaks down the page

[rapha]

Hello,

I was recently handed down an HP M605 printer that was stored unused for more than 7 months. The print quality is actually okay for letters/documents, but the problem appears once there are filled regions in the page.

Whether it's a solid black or shade of gray, there would be white faded streaks down the page, and they would always be in the same position.

I've already tried cleaning the transfer roller, but it didn't help. Has anyone encountered this already before? What part of the printer should I be looking at to solve this problem?

Thank you

Toner carts degrade after not being used for a time.
Bet it was stored in an area that wasn't kept in a environmental controlled area.

Looks like most lasers that have set for months do. Toner separatess from the developer and settles to the bottom of the development unit. This causes the developer to go south in a hurry and sometimes the development unit as well.

dev units in these machines are built into the toner carts... they are AIO's.

It's a mono component system.
Replace the cartridge

Thank you everyone for the suggestions.

Yes, it was just stored in a covered but open-air location. Moisture during rainy days could have ruined it. When I took a peek inside, there seems to be a roller of rubber material in contact with the drum. The rubber material seems to have white streaks and blotches on it as if moisture seeped deep into the material then dried very slowly. I really do hope it's just the cartridge and not something that's not user-replaceable.

The toner cartridge still has 8,000 pages or so to it (out of 10,500), so will try to remember to report back once I get to swap it with a new one.

The cartridges come with an electronic chip and I'm not sure if swapping a new one and an old one back and forth is possible.

just replace the toner cart and be done with it...

hopefully it is a Genuine OEM HP toner and not some 'turd party' toner.

Yes, both current and spares are Genuine HP toner cartridges. Letters and documents print just fine, so will just keep using it for now.

Probably in two months' time I will get the chance to swap the new one in.

Many thanks again!

glad to help!

*Side note... don't upgrade firmware to the latest IF they EVER want to use 3rd party toners... it will prevent printing and give a message

Unsupported supplies or something like that.

Thanks for the tip, I'm also aware of that. Can't blame HP if third-party components really do damage their products and consequently their image. I heard they even went as far as removing the old firmware versions from their website so you won't be able to downgrade back.

Too late though, I already upgraded the firmware to latest. But it's alright since we don't plan to use 3rd party toners anyway.

I personally find the printer to be very well made and a joy to use, it just doesn't feel right to pair it with anything else other than original cartridges.

After market supplies have always been a problem. Years ago a local RV dealer called because their small HP Laserjet started making dirty print. I went out to check it and the first thing I noticed was that they had a rebuilt cartridge in it. I asked if the old catridge was still around and she puled it out of the waste basket. I shook a few time to loosen any remaining toner, put it in and ran a test print - perfect.

that's why I call them " turd party " toners.

Don't know if you got back to checking this machine. Since you mention "that rubber roller", it's the transfer roller. It's rather rare you have to replace them, but they do occasionally get bad. It's a cheap and easy part to replace.

he said he cleaned the transfer roller he also made note of this:

there seems to be a roller of rubber material in contact with the drum. The rubber material seems to have white streaks and blotches on it as if moisture seeped deep into the material then dried very slowly.


that roller he is talking about is the PCR primary charge roller located in the Toner cart. problems with the PCR can cause all sorts of problems.

if he felt adventurous he could dismantle the toner cart .. remove the PCR and clean it with Nu Finish car polish .. apply .. buff off.. apply ..buff off.

It can take up to three applications to clean the PCR properly ( this was a trick I learned decades ago working for a company that refurbed HP toner carts)
