Genuine OEM Toner and Ink vs. Compatible, Third-Party, or Refurbished

While I don’t get as many questions about the different types of toner or ink anymore, I see a lot more people using compatible, third-party or refurbished toner in color machines. Unlike must monochrome machines, in color machines non-OEM toner can result in major quality issues and expensive repair bills. In this post, we’ll explore the difference between monochrome and color machines as it relates to toner, and discuss some of the issues I’ve seen with non-OEM toners.

OEM (Original Equipment Manufacturer) – Toner cartridge made by the manufacturer of the product, which is specifically designed and tested to insure the best quality of print and longevity of the product. This is also referred to as “genuine”.

End User Tips on Fixing Common Problems

Every printer is bound to have problems arise over its life time. Some problems will be easy enough to fix that your customer can handle it. Other problems, of course, require the skills of a professional service technician. In this article I will touch on some of the easy fixes that customers can mostly likely handle on their own.

Tip for Service Companies
There are many reasons why some of the easy problems most customers can handle on their own can effect a service company’s reputation. While it’s fun for us techs to go out to a customer’s office and tell them they just have a defective toner or clean white-out off a glass strip and charge a fee, our goal is to make our customers happy. One key to doing that is to make sure they don’t see us all the time to fix minor issues. If your customer’s Accounting Department sees constant billings from a service provider they start to wonder if they are doing a good job. It might not be the techs fault, but the customer paying the bills might not see it that way. While educating your customers with a few tips might, at first, seem like a bad idea from a financial point of view; it can go a long way toward promoting a trusting, honest relationship with your customers for a lasting relationship and a good reputation.

Of course not all customers care about fixing their own printers. Some just want the printer fixed and done whenever there is any kind of problem so, when attempting to give tips and advice, pay attention to your customer. If they seem uninterested, cut the conversation short and move on. Not everybody cares for free advice.

New OEM Parts, Refurbished, and Aftermarket Parts. What’s the difference?

In today’s competitive office equipment market it’s vital to make the cost for repairs of equipment as low as possible to make it reasonable to fix vs. selling a new machine. Servicing a small to midsize machine is definitely more profitable then selling a new machine. Therefore, everybody is searching for parts and consumables that are high quality and sold at a low cost. Large manufactures are more interested in selling new machines with lower cartridge yields realizing that they will make their money selling consumables for the product vs. selling parts. If you try buying parts from most manufacturers you soon realize the parts, if available, cost half the value of the machine. In this article I will discuss the difference between the variety of parts and consumables that distributors are providing so when you decide to make a purchase you have a better understanding of what you are getting for your dollar.  Continue Reading

HP LaserJet 2400 Series; Noise in Rear of Fuser

The 2400 series of HP printers are prone to excessive noise in the rear of the machine. Unlike the P3005 engines where, typically, the noise is more gradual and seems to take longer to generate service calls, the 2400 series tends to really develop it’s noise problems at 40,000 to 45,000 copies and it can get extremely bad around 70,000 to 80,000.

In the HP 2400 series printers, while the noise problem appears gradually, it seems to greatly worsen in a short amount of time. I see a lot of service calls generated for this specific problem, unlike with the HP P3005 model where it’s kind of a secondary issue…“Oh yeah, and it seems to be running louder now then when we first purchased it.” I find than many users are afraid to continue to use the 2400 series because it sounds like parts are being destroyed. So identifying the problem in this model is easier and the fix is much more satisfying, because the printer is drastically quieter after it’s been repaired.

What to do on a service call
First, run a few prints, including the configuration page, to check the machine’s usage, overall condition, and its noise level. Then remove the fuser and check out what‘s happening in the rear of the machine, following these directions: Continue Reading

Laser Printer Firmware Updates

More and more, service technicians are getting questions about firmware from customers. What is firmware? What is the difference between print drivers and firmware? Why is it so important that I update my printer’s firmware? Why haven’t I heard of firmware before now?  Sound familiar?

Printer manufactures have made firmware available and if users call in for support, they will ask if they’ve updated the firmware. On some recent models the software installed with the printer periodically updates the firmware. So why haven’t the manufacturers done a better job explaining the importance for firmware to the end-user? In this article I’ll shed some light on the subject.

What is Firmware?
Firmware, in my opinion, is best described as your printer’s internal operating system. Without it the equipment can’t do anything but turn on. [Side note: engine tests are run by firmware stored on the DC controller — for all you tech’s thinking I’m a liar.] Everything from your $20 TV remote to your 50k sports car has firmware. Fifteen years ago a printer went through an intense testing period and the majority, if not all bugs were worked out before it was presented to the end-user. Going back to the operating system example, a very basic command system like DOS was used. Pretty much if you had an error it could usually be traced back to the user.

However, in today’s market our printers are much more complex and the demand on development is forcing us to create newer cutting edge equipment with less attention to perfection. There are different speeds, scanning, fuser modes, usage profiles, etc., much like the Windows O/S, where everything is more user-friendly and with many options, but prone to more problems. So, like Windows updates that appear every time you turn on your computer, you have printer firmware updates that also need to be installed to fix operating glitches so your equipment can run at peak performance and you can reduce service calls and expensive repair bills.

Drivers vs. Firmware
Now that we’ve established that firmware controls the function of the printer, let’s explore the difference between drivers and firmware. Drivers take the information from your computer and convert it to a language that your printer can understand. Firmware, along with the formatter, takes that information and sends it to the rest of the machine to perform the actions necessary to put the digital data on paper.

Why are firmware updates so important?
This is the confusing part. When you call your manufacturer for tech support you’ll be asked for the make and model number of your printer, its serial number, and now for your firmware version. If you’re not running the latest and greatest firmware version, you’ll need to update it before you can proceed. However, you’re thinking ‘my printer worked fine for years with the old version, why not now?’ Once again, firmware is like your computer software, it has glitches. One day you’re using Word with no problems and the next day you go to open it up and you get a missing file error or a corrupt data message. After uninstalling and reinstalling, you’re back in business. Same with firmware, it too has glitches. The main thing is to fix the glitches before they become an issue.

Firmware fixes a wide range of problems. It can fix printing issues with certain software, fax and scanning issues, error codes that will not clear, and its even been known to fix certain issues where parts of the printer overheat and get destroyed.  Those are just a few of the possible fixes.

Most firmware updates work only if the printer is at a ready state. If you wait until the printer is in an error state and then realize that a firmware fix will keep the issue from happening, you’re too late. You can no longer perform the update and you have to replace the board that has the firmware on it.

If your fax LIU overheats and needs to be replaced and you find out there was a firmware fix for that issue, unfortunately, you’re too late, again. That’s why it’s best to keep firmware up-to-date and understand what fixes are being addressed in the current version. Most manufactures provide this information with the firmware download or in a readme file with the download.

The downside of updating the firmware
If a printer fails during an update you can permanently corrupt the firmware, the printer will not go into a ready state and you can’t try again. So, if an update fails, then you’re most likely stuck replacing the board. Right now there are very few printers that can work around this issue. That’s why it’s so important to read and follow the instructions when performing this action.

Things to remember when updating firmware
Be patient; update when you know no one else is going to be printing; don’t ever unplug power while updating; and, most importantly, the computer almost always finishes before the printer so once the computer says it’s done go over to the printer and wait until it’s complete.

Just remember [for the paranoid individuals like me], for every firmware update you read about going bad – thousands are going right. So be cautious, but do it when it needs to be done. Otherwise you could be buying a new printer or looking at an expensive fix.

Why are users just now hearing about firmware?
Firmware has been around for quite some time; basically since the beginning of electronics. As I mentioned earlier, when laser printers first came out they were very basic and there wasn’t much input the printer needed. Firmware used to be integrated on the logic board and if it ever failed you were stuck replacing the board.

Printer manufactures did a lot of research and spent a lot of time to make sure this didn’t happen. About ten years ago manufactures started making firmware DIMM’s, which looked very similar to memory DIMM’s. They were installed in a slot on the main board. If the DIMM went out or needed to be updated you just swapped it out, bringing down the cost of repair.

As time wore on, more fixes were being made and firmware was being updated more often, leaving manufactures throwing old firmware away or not having it available because they couldn’t predict the demand.

Now, almost all manufacturers use a flash ROM chip located on one or more of the logic boards. This way the firmware can be updated whenever needed.  Like I said before, the modern printers are much more complex. Thus, the possibility of more problems.

Allowing the end-user to fix their own issues through firmware helps keep a printer working for a longer period of time. Printer manufactures hope this will extend the life of the printer and reduce the costs associated with maintaining it.

Links to firmware for four of today’s leading printer manufacturers
For most manufactures you can find firmware updates in the same locations you would the print drivers. Typically if firmware is available for download you will find it there. If you do not see a download listed by your machine then one is most likely not available yet or your machine doesn’t have a flash chip or DIMM in it.

The Lexmark firmware requires a special code. From what I briefly read it’s related to your printer’s model number, which can be confusing if you not familiar with their system.  Basically they don’t want you loading the wrong firmware and permanently damaging your printer. So, if you call Lexmark support they will guide you through getting the right firmware for your machine.
