HP LaserJet 4200, 4240, 4250, 4300, 4350 Common Errors and Issues


Yet another great series of printers introduced in the 4000 line of printers by HP, these machines are the workhorses that we’ve come to expect from HP for fast every day printing. They experience very few problems and have long life spans. The majority of the problems are easily fixed and at a relatively low cost to the customer making these printers a favorite in any work environment.

In this article, I will discuss a few of the issues related to these machines to help make repairing them as trouble free as possible.

13.01 Paper Jam Error
Not the most common error but it still does occur on these printers.

Common Error Codes and Problems with the HP LaserJet 4000, 4050, 4100


In this article I’ll discuss the variety of common service related issues in the early HP 4000 series printer family. You may be wondering why I’m focusing on these older printer models.  In my opinion, next to the HP 4 and 5 series, the HP 4000 series is one of the best lines of printers ever made. Many of these machines are still in the field and, due to age, some of these problems are becoming more frequent. Because these machines have become “more repairable” over the last year since the price on the parts has drastically dropped and the cost of the toner cartridges have gotten lower, they are some of the cheapest machines to run given the cost per page. So for your customers who are thinking about how they can get the most for their money, these machines offer what they are looking for.

NOTE:  Almost all the part numbers listed in this article are for the 4000 series. The 4100 uses different part numbers for the feed rollers, pick up and feed assemblies, and the paper size board is different on some of the models given the extra feed trays.
