4015 Not recognizing toner cartridge

[HenryT2]

We have a 4015 in the shop that will recognize the cartridge as a genuine HP cartridge, but, then displays ' Install Black Cartridge '. We have tried different cartridges, the sensor is good, and still getting the error. We are getting +5VDC on both pins 1 & 2 at J74 on the DC controller board.
Has anyone had this problem? Any suggestions will be appreciated.

Possibility: There is one round contact on the left side of the cartridge that looks like a oversize pin and should connect to the machine when cartridges are inserted.The contact provides bias to components inside the cartridge, such as supply Roller, Doctor Blade,etc. Should this supply not be established, the machine system will read that there is no cartridge in the cavity. All this can take place after the chip is read and when the machine is trying to initialize.
Check such contact in the machine and inside the cartridges if need be.

Thanks for the suggestions, Hank. We tried that ...but, it did not help.
We were finally able to get thru to HP. They decided that we need to replace the Formatter Board. We'll see if that corrects the errors, and up-date this post.

This may sound silly, but are the cartridges the right kind (CC364A or CC364X)?

[Hank]

This side of the woods I find the CC364A toner cartridge which is low yield and the CC364X high yield, both used in the P4015 . By design the CC364X will not normally run in the P4014, only the CC364A does.
Never confronted a problem such as hinted here with the formatter, therefore I will look forward to learn how was it solved.Thanks

UP-DATE........

We did double check the cartridges and are using the correct ones.

We finally got in the formatter board that HP said would fix the problem. YEP......THEY WERE WRONG !
Still getting the errors. Contacted HP again; now they say it is the PAG holder assembly. We had already tested this with the meter, and it appeared to function correctly: ( this assembly is located beside the laser ) It's on order and we'll try that next to see what happens and let you know.
Hank and Blackcat... thanks for the input.

This may or may not have anything to do with your problem, but at this point you may want to try just for fits and giggles.

Check the cartridge guides in the printer to make sure there are no obstructions or that they are out of position. It may prevent the cartridge from seating all the way in.

Remove any optional equipment (Jetdirect cards, opt feeder/trays, duplex unit, or HDD's). They can cause flaky errors to show up if they are defective.

Check the top cover to drive linkages as well.

Thanks Prntrfxr. We did check all the guides, and the printer was ' stand alone ', Jetdirect is enbedded.
Today HP says it may be the the power supply. This makes more sense than the PAG holder assembly.
Got those on order, so we'll see what happens.
Thanks to all for the input and suggestions.

Henry, did the power supply fix this issue?

[HenryT2]

Well...........Hey prntrfxr.........

How's things over in the east ?

" Henry, did the power supply fix this issue?"

NO : IMAGINE THAT !

We did find what we believe to be the problem....waiting on parts from HP to try this.......

On the mid-section , left side , there are two contacts that are under the toner cartridge ; Bias , or ground , tabs probably.

Well, we noticed there was only one , not two. While the end-user had this printer on-site, they possibly had a paper jam and bent this wire. We think that when they put the toner cartridge back in , the bent piece was pushed down completely under the mid-unit . No contact ... does not recognize the cartridge as being installed .

We will let you know how this works out when we get the springs ( HP does not have a part number...will have to make one up ... find the part ... then ship it to us .) That may take a while .

ANYWAY ... keep everything runnin' right over there .
