Printer Cartridge Empty Error

In this last year I haven’t been able to get away from servicing the HP Color LaserJet 5500 and each call I get seems to present an even odder situation than the last one. In this article we’ll explore the Empty Cartridge Error,  how it presented and what ended up solving the problem.

The Reported Problem
The customer explained to me that, one day as they were printing, the machine reported that the three color cartridges (cyan, magenta, yellow) were empty. The customer ordered OEM replacement cartridges but once these new cartridges were installed the error did not go away — the black cartridge still said it was half full but the color cartridges said empty.

When I arrived onsite I first tried reseating the cartridges and cleaning out the cartridge contacts. Second, I disabled the cartridges in the diagnostic menu and printed several test pages. The machine hadn’t reported any errors related to the cartridges and the firmware was up-to-date. Continue reading

Broken Paper Trays and Feed Issues in HP P3005 and P3015 printers

In the last few weeks I’ve had to replace four trays for machines that had broken paper stops. I believe a lot of these problems stem from customer misuse/abuse.

In general, I go out on these calls because the machine has been having issues for quite some time and finally the paper stop breaks in the rear of the machine causing the machine to stop printing completely.


As the pickup roller in the tray wears down the machine struggles to feed paper out of the paper tray. Customers tend to fill the tray full with paper, which helps in the short-term for feed issues but doesn’t fix the underlining issue. Over time, even a full drawer of paper doesn’t alleviate the problem. Plus, after overloading the paper tray and slamming it in and out repeatedly the stop at the back of the tray breaks leaving the tray useless.


Let your customer know — instead of struggling with feed issues for months, getting frustrated and taking their anger out on the feed tray, a visit from their service tech to diagnose the problem and repairing/replacing the worn parts on the machine will prevent additional damage and repair costs. Purchasing a new feed tray can double a repair bill; roller and sep pad replacement is easy and inexpensive.

And, with a little technical savvy, the users may be up to the task of replacing the roller/sep pad themselves.

If you’re a user and find that your printer is having feed issues, order the parts listed below and follow the easy to understand instructions found in the service manual at Market Point’s website to avoid unwanted repair cost.

HP LaserJet Pro M1536dnf Paper Jam Error

I was called out to work on a M1536DNF for a customer who informed me that while installing a new toner cartridge, part of the machine broke inside and then, after every print, the machine recorded a paper jam. If the customer opened and closed the toner door the machine would proceed to print another page then record a jam. Obviously this got old very quickly and the printer needed to be checked out. Upon arriving onsite I noticed the broken part was the delivery assembly. Unfortunately, this assembly is part of the fusing assembly so the whole fuser needs to be replaced if this part happens to break.

This machine ended up being under warranty so I called HP and got the machine exchanged. Usually when I call HP it takes about an hour of troubleshooting and another hour to setup the warranty service. This time, however, it didn’t take long as the customer rep on the other end was well aware of the issue.

This service information is more of a general tip to those of you in the field servicing these machines or planning on selling them. The delivery assembly is somewhat fragile and replacing the toner seems to lead to this part breaking. HP noted that this often happens when the customer fails to remove the shipping tabs. So whenever servicing these machines I will be informing my customers of this design flaw and warn them to handle this area with care in the future. If you do find yourself needing to replace the fuser outside of warranty, the part number is RM1-7576

HP CM1312 and M2727 Multifunction LaserJet ADF Paper Jams

This past week I had a few calls on these models so I thought I would share some information about these document feeders because they can be found on several different models of machines made in the same time period as these. Below are the two most common issues I find with these units.

Scenario 1 – Not Feeding into the unit
Due to the fact that paper is fed face up through these document feeders, toner, ink, and dirt seem to contaminate the pick up and feed rollers more often than face down document feeders. To clean, open the ADF feed cover, Continue reading

Issues Related to the HP P3015 LaserJet Printer

Today, let’s discuss three common problems with the HP P3015 model printer.

But first, let me say that for whatever reason, I haven’t gotten many service calls on these machines. And, from seeing what other technicians say on the online forums, they haven’t encountered a lot either. I don’t know if companies just weren’t buying them because the P3005 printer had so many problems and they thought the P3015 model, being the newer version, was going to have the same amount of trouble, or if it was the price tag.  Companies could buy the P4014 or P4015 for not too much more. And ven the reputation of other HP 4000 series models, they might have gone that way being pretty confident the P4014 or P4015 was a safer bet.

One other caveat: every one of the HP P3015 printers I’ve serviced has had over 100,000 prints and had never been previously serviced. I’ve seen one that had over 200,000 prints and the fuser still looked great. So it would appear HP realized they had a huge problem with the previous model and has taken great strides to return the 3000 series to what it was intended to be.

OK – that’s the background from my perspective, now onto some troubleshooting…

Another Perspective on Copiers vs. Printers and Lexmark vs. HP

Whether you call them copiers, printers or MFPs, the convergence of copy/print/fax/scan has created a blur in our use of the terms. Today, most people use “copier” when they are really talking about a multi-function printing device (MFP) that does copy, but also prints, faxes and scans.

OEMs who started out in the traditional copier market, such as Xerox, Ricoh, and others, and the companies that sell and service those brands, refer to them as copiers. They are the “office machines” businesses who have traditionally sold to office managers, purchasers, etc.

OEMs who started out in the laser printer business, such as HP and Lexmark, and the companies that sell and service those brands refer to them as printers or MFPs. They are the “printer” companies who have traditionally sold to IT departments.

Those lines are now blurred. Copiers print and printers copy. For the sake of clarity in this post, we’ll refer to them all as “copiers”.

We are fortunate to have two very talented service guys on this blog, Kevin Gumpp and Brian Ude.  They each have a unique perspective on the HP vs. Lexmark market in the world of MFPs. Read the ‘HP Guy’s’ perspective here.  Then check out the ‘Lexmark Guy’s’ Perspective below.


Let’s examine another reason HP might not be predominate in the copier market

And why, in this service guys opinion, they should lose some of the market share they have in the printer market.

It’s simple, HP’s service and support, beyond the major metropolitan areas, is virtually non-existent. Yes, almost anybody can get parts and supplies but not from HP and definitely not for warranty and service packs. Continue Reading
