M477, 60-02 error code...

[Oystercopy]

Hey guys... new to this box, no idea what could be wrong.

Customer is about 40 miles away from me, so hoping to get some help before I go out there.

Thanks in advance!

60.02 - Tray 2 lift error

Remove from surge protectors if applicable
Replace the Tray 2 Paper Cassette - RM2-5469-000CN
If the error persists, replace the Paper Pick-up Assembly - RM1-8045-000CN

Re: M477, 60-02 error code...

I work on these a lot and can most of the time fix this error.

Likely cause paper wedged in the pickup area, feed / separation tyres popped out of position.

Sometimes the pickup roller is causing the error because it's in the wrong position, this is due to a sticky solenoid in the pickup assy, and the rollers are not in their "home position"

There's also this webpage (if you can make any sense of it)

I see what you mean. All the pictures are the same.

Glad I'm not the only one.

Re: M477, 60-02 error code...

Yeah, thanks for those pictures, but it didn't look like it was able to tell you much.

So, if its not something obvious like paper jammed up into the lift assembly, am I looking at replacing the lift assy? Or what about that "spring" and where is it?

Re: M477, 60-02 error code...

It may be the lifter assy but if the pickup roller is stuck in the lowered position the paper lifter hits this and generates 60.02

You will see when you get there.
Take a set or tyres they wear out

Re: M477, 60-02 error code...

It ended up being a jammed piece of paper which was partially in the (duplex?) guide assembly and partially in the feed rollers. There was also a small sliver of paper in the feed guides, directly after the feed rollers also. Gosh, those are TINY rollers... I don't know how they would even last 5K on that box?

Re: M477, 60-02 error code...

Paper feed lift mechanism, to get to, you have to disassemble to about frame to remove. If it isn't that, main pwb. Either way, not worth the time and trouble. Just had one a week ago. Good luck. Would try pwb first. Easiest to remove and check.

Just had this error today, paper pick up roller slightly out of position.
With cassette installed 60.02.
Restart with cassette removed and paper in manual feed, it works, put cassette back in all good!

Weird.

The only thing good about these machines is the ability to get cheap aftermarket toners on ebay. Fusers are expensive, don't last long, and are a pain to change. Make sure to turn off automatic firmware updates, HP has gotten sneaky and cheap and has been sending out updates that will disallow aftermarkets like they don on the newer models. Hasn't hit this model yet, but I'm sure it's coming.

Re: M477, 60-02 error code...

Had this error today 60.02 with cassette installed, with cassette removed and paper in manual feed it got to the ready state but when trying to print the machine made all the right noises but didn't feed the paper.

On closer inspection I noticed the separation roller was pressed against the paper feed roller, normally there is a gap of about 4mm between these rollers. I was convinced it was a problem with the cam on the pickup assy.

Here is what it looked like when I took it out. The cam is out of position.




Here is the "home" or correct position




This might help someone insane enough to attempt this repair !
