Laserjet 5000 Error 50.2 Fuser Error

[mavon]

:cool: I have a Laserjet 5000 printer which has an error code 50.2 Fuser Error. Cycled power - took out fuser - reseated - still have same error. I'm thinking its most likely the fuser has gone bad but I suppose it could be the power supply also. Any way to know for certain? I have a digital volt meter and can check resistance across the pin outs of the fuser, but what pins and how much resistance?????

I'm also a little confused about Fusers. The fuser part number in the printer is RG5-3528 but I also find fusers for the same printer using part number RG5-5455. Will they both work??? Also does anyone have a used fuser for the LJ 5000 you might want to sell???

The HP service manual says to check for continuity between connectors j1307-1 and j1037-2 then check for continuity between j1308-1 and j1308-3. If either are open replace the fuser. The photo on the page shows 4 large connectors and 4 small connectors all ligned up. The 4 large connectors are above the 4 small connectors the large ones are j1308-1 through 4. A 50.2 error is the fuser warm up service. It also says to shut the printer off for 20 minutes to clear the error.

I took the HP LaserJet course 2 weeks ago so I don't have any experiance yet. I have to check the book.

With our Lord's blessings,

RG5-3528 is the old part number for the LJ 5000 fuser, RG5-5455 is currently being used. HP & Canon often changes part numbers and I've seen a different part number show up on some of the recent shipments of 5000 fusers we've received.

you can measure the fuser and the resistence should go around 100ohms and the thermistor should have 300 or400 k ohms.normaly is the resistence that opens
