I’ve been out on service calls and have seen, or heard, unusual things happening in the exit area of the HP 4200/4300 printers. What I’ve noticed is that sometimes the paper feeds through normally but with a little extra clicking or snapping noise. Other times the noise is accompanied by the paper not feeding through properly.
Problem There are two exit flags that paper has to go through as it exits out of the machine to the face-down delivery area. One right-side flag is for the face-down bin-full sensor and the left side flag is just to provide equal pressure on the paper to the right side flag. On the bottom of the top cover HP has put two dampener pads like what you see on a solenoid. Over time these pads wear out. Continue reading →
The HP P4014 and P4015 printer model offers the same great quality we’re used to when we think of the 4000 series printers produced by HP. These machines offer fast print speeds, high print volumes, few service calls, and inexpensive parts making repairs cost effective for customers. In this article I’ll point out a few of the minor problems with the 4014 and 4015 models, discuss a little about the differences between the two models, and why end users, techs, and sales representatives should be cautious when making buying decisions.
Slow Start Unfortunately, these printers were first introduced at the time of the stock market crash in 2008 and 2009. Companies were downsizing. Large companies found themselves with extra printers or budgets that didn’t justify replacing a printer when their old faithful 4200 or 4250 could be repaired for a third of the cost of a new machine. And the market became flooded, and still is, with slightly used 4200 and 4250’s with low page counts that look brand new and are available at a low cost.
I’ve found that many large companies like the fact that they have several printers that use the same toner cartridges, making ordering and supplying more efficient. Continue Reading
By far the most troublesome part of these HP machines is the fuser and swing plate assembly. Due to the increased print speed of these models and the heavy usage the printers handle, the fuser and surrounding gears tend to receive a lot of the abuse and wear. Noise is the main issue. If you work on these machines expect to receive a lot of calls related to noise and jam issues in the rear of the machine. Mainly in this article I will focus on noise issues but I’ll also take a look at other problems related to the fuser. Continue Reading
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. Obviously, the first thing to check is the feed separation rollers (part # RM1-0037) The rollers for the 4200 and 4300 series tend to last a lot longer than original 4000 rollers but they still wear out so check to make sure they still have tread.
