HP LaserJet 4200/4250/4300/4350:

An Easier Way to Replace the Swing Plate Assembly (RM1-0043)

The swing plate assembly, a small obscure assembly in the right rear of the HP LaserJet 4200/4300 series of printers, has recently become very popular. Why? One reason is that, obscure as it is, it has a very important job: to couple the printer’s main drive assembly to the fuser. The other reason is that if the fuser isn’t fully seated (which is unfortunately a common problem in this series of printers), it will “bounce” when the swing plate attempts to drive it. This can damage both the gear in the fuser and the gear in the swing plate. The standard remedy for this condition is to replace both assemblies (fuser and swing plate).

The fuser is relatively expensive but very easy to replace. The swing plate is just the opposite: relatively inexpensive but very difficult to replace, at least by conventional methods. A recent article in another publication detailed a procedure for replacing the swing plate assembly that involves disassembling much of the printer, and that will take an hour or two, even for an experienced technician. But in most cases, this full procedure is unnecessary. There is a much easier way, provided certain conditions are met.

If you look at the swing plate assembly (see figure 1), you will notice that it has two gears. One of them (white and on the left in figure 1) couples to the main drive; the other one (black and on the right in figure 1) couples to the fuser. If both gears are damaged, you will have to replace the whole assembly, and this article won’t help you. But in the majority of cases, only the fuser drive gear is damaged, and it is surprisingly easy to replace just this gear.

Figure 1: The Swing Plate Assembly

At present, you cannot buy just the fuser drive gear (but see note at end of article), but you can buy the swing plate assembly (still a relatively inexpensive part), remove the fuser drive gear from it, and install just that gear, thereby saving yourself a great deal of labor.

We would recommend starting by disassembling the new swing plate assembly, to get a feel for how it comes apart, before you disassemble the one installed in the printer. Note that the fuser drive gear is secured by just one screw. Remove that screw from one side, then push the gear shaft out the other side, and now you should be able to remove the plastic spacer disk, and finally the gear. Figure 2 shows the swing plate assembly with these 4 parts removed. Note the orientation of the disk and gear as you remove them.

Figure 2: Disassembled Swing Plate Assembly

The next step is to remove that same gear from the swing plate assembly in the printer. You’ll still have to remove a few other things to get to it, but not nearly as much as in the full procedure described in the other article. Here’s our procedure:

If the printer has the optional duplexer installed, remove it by lifting it slightly and pulling it away from the printer.
Remove the rear output bin by opening it, squeezing the hinge pin in the right rear (on your left if you’re behind the printer) out of its mounting hole, and then rotating the bin until the hinge pin is free. Now you can just slide the other hinge pin out of its mounting hole and remove the bin.
Remove the fuser by squeezing the blue release tabs and pulling it straight back out of the printer.
Remove the formatter cover (in the right rear of the printer) by pulling/sliding it to the rear (see figure 3)

Figure 3: Removing the formatter cover

(slide in direction of arrow)

5. Remove the formatter board by removing 2 screws (see figure 4) and then sliding the whole metal cage out the rear of the printer (there will be some resistance as the self-mating connector unplugs).

Figure 4: Removing the formatter

(arrows show the 2 screws)

6. Now we can get to the swing plate assembly and the fuser drive gear. The single screw that secures the fuser drive gear is accessible through a conveniently-placed hole in the printer’s right side frame (see figure 5). The procedure from here is identical to what we did with the new swing plate assembly earlier, except that you’re working in closer quarters: remove the screw, then push the gear shaft out the other side (see figure 6), remove the plastic spacer, and finally remove the gear. Re-assemble in the reverse order (make sure to install the gear before the spacer), using the new gear in place of the damaged one. Make sure to observe correct orientation of the gear and spacer. It will take a bit of patience to manipulate the various pieces so that all the holes line up and you can insert the gear shaft (it may help to lay the printer on its side so that you're not fighting gravity), but this is still much less work than replacing the entire swing plate assembly.

Figure 5: Right Rear Frame of Printer

(red arrow points to the screw that secures the fuser drive gear)

Figure 6: Other side of Right Rear Frame,

showing fuser drive gear (red arrow)

and gear shaft (green arrow)

Remember that if both gears are damaged, you will have to replace the whole swing plate assembly. Fortunately, this is rare. It’s easy to visually inspect the fuser drive gear by just removing the fuser, but how can you check the other one? The best way is by performing the procedure described in this article! Once you have removed the fuser drive gear, you can visually inspect the other one (a flashlight may be helpful). If it’s in good shape, you can just carry on with the rest of the procedure we have described. If this other gear is damaged, you will have to replace the whole swing plate assembly, but you haven’t lost any significant time, because that procedure still requires removal of the fuser, formatter, etc.

However, we are confident that in the vast majority of cases, the procedure we have described will get you going – in a fraction of the time that the other procedure would take.

Note: Since this article was written, more options have become available for obtaining the swing plate and fuser parts. You can still get the whole fuser and/or the whole swing plate assembly, but the following parts are also now available:

RM1-0043-GRB Fuser drive gear and spacer (unlubed) from swing plate assembly

RU5-0016-A 40T gear for 4200 & 4300 fusers

RC1-3324-A 40T gear for 4250/4350 fuser

5851-2766-N OEM kit, includes swing plate assembly and 4250/4350 fuser gear

(this gear also works on 4200 & 4300 fusers)

In HP laser printers, the network configuration is stored on the network card (also known as the JetDirect card or EIO card), not on the Formatter board. Therefore, you need to reconfigure whenever a network card is installed or replaced. There are numerous ways to configure the network. Here’s what we recommend:

First, before attaching the printer to the network, install the card into the printer, power up, and then go into the printer’s “EIO x” menu (“x” represents the slot number that the EIO card is in). Menu structures are different in different printer models, so printing out the menu map may help you find this menu. Setup details also differ from one model to another, but in general, assuming that you have an Ethernet network (10Base-T or 100Base-TX) using a TCP/IP protocol (by far the most common), the basic steps are similar:

Tell the printer that you want to configure the network (“Configure Network = YES*” or something similar).

Select “TCP/IP” as the network type (you may also have to set “Configure TCP/IP = YES*”).

Select “manual” as the configuration method (other choices are “BOOTP” or “DHCP” – in some printers, you may have to set “BOOTP = NO*” and/or “DHCP = NO*”).

Enter 3 groups of numbers: IP Address, Subnet Mask, and Default Gateway. Each of these is configured as 4 bytes. For example, if the IP address is 10.1.1.24, “Byte 1 = 10”, “Byte 2 = 1”, “Byte 3 = 1”, and “Byte 4 = 24”, and these are the numbers you would enter. Ideally, you will have a record of the previous configuration, so that you can put in the same numbers. If not (or if this is a new installation), you can always assign new numbers. However, you can’t just put in any old numbers (in particular, if there are multiple devices on the network, you can’t use the same numbers as any of the other devices!), so it is best to consult the customer’s IT personnel at this point.

Now power down, connect to the network, power back up, and print a configuration page to verify the network configuration. In most cases, you’re done at this point, but some operating systems will have trouble finding a printer even after the address has been defined. So we recommend running HP’s “Install Network Printer Wizard”, which can be downloaded for free from HP’s website (www.hp.com) – just type “Install Network Printer Wizard” into the search window and you’ll find it. This program will step you through the installation of a new printer, and will also help the network find an existing printer. (NOTE: You can also do all of this with HP’s “Web Jetadmin” software (also available as a free download), but this is much more complicated, so stick with the software described above unless you are an IT professional.)

Among the most common problems that you'll see in the HP LaserJet 9000 is the false 13.20 error. It will come up during or immediately after the power-up sequence, before you even try to print anything, and you won't find paper anywhere in the paper path. As in any printer, this can be caused by a stuck sensor flag, but in the 9000, there are some other potential causes: a defective fuser or DC Controller board, or bad high voltage connections.

Because this error often comes up after installing a fuser, it's easy to assume that the fuser is the cause. But it turns out that the 13.20 error is much more often caused by the DC Controller, even when you get the error with one fuser but not with another. Here's why: the 9000 detects "wrapping jams" (paper wrapped around a fuser roller) by making an electrical connection to the conductive coatings on the fuser rollers. Early versions of the DC Controller board had a very narrow tolerance for this measurement, and natural variances in fuser conductivity put many fusers outside the acceptable range - even though there was nothing wrong with these fusers.

HP corrected this problem on later versions of the DC Controller, but many printers still have the older versions, and on these printers, it's hard to find a fuser that the printer will accept. To check the DC Controller version, print a configuration page and look at the "printer number" (a two-digit code ranging from 15 to 1C). If the second character is a number (5-9), the printer has an older DC Controller, which will be more likely to cause false 13.20 errors. On newer versions, the second character will be a letter (A, B, or C). All DC Controllers sold by Computer Care are the newer versions.

The bottom line is that by making sure that the DC Controllers are up-to-date in all of the HP LaserJet 9000 printers that you service, you can greatly reduce 13.20 errors and fuser warranties.

Introduction
are hexa-decimal based numbers generally
caused by internal system errors. The following pages contain a list
of and their respective descriptions and
recommended corrective actions. Only try one recommended action
at a time and check if the error code has disappeared.
Continuable and Non-Continuable Error Codes
Some of the Error Codes are continuable, which means you can
press Enter on the front-panel and continue working with the
Printer. Non-Continuable Error Codes do not allow you to continue
working with the Printer, in this case power the Printer OFF and ON
again and see if the System Error disappears. If the Error Code
reappears, then the Printer requires an on-site visit in order to
resolve the problem.
NOTE
Even though the customer can continue working with a
Continuable Error Code, an on-site visit should still be planned
to troubleshoot the problem.
