LaserJet 4Si error: 53.00.02

We're getting the "53.00.02" error on our HP LaserJet 4Si. We have found that, if we hit CONTINUE when a job gets stuck, it will print the job, but we have to hit continue after each job in the que.

The official Operator's Guide says the following:

53.XY.XX error - An error occured on a ROM/RAM SIMM.
Click [Continue] to continue printing. For information on the XY.ZZ references, see the LaserJet 4Si Printer User's Reference Manual.

One of our technicians recalls upgrading/changing the memory chip in this printer years ago. Accorinding to documentation, it might be a 4MB SIMM module, but I am unable to figure out how to access inside the printer, and thus cannot verify that.

I guess my question is three-fold. [1] I'd like more information on this error. [2] How do I access this memory module? [3] What do I need to replace it with to try and clear the continuing error?

You can remove the SIMM. If you don't do memory intensive jobs, you don't need it. To access the chip, you have to remove the right plastic side panel (looking from the front of the printer). There are 2 screws at the bottom of the panel. Once that's off, you'll see an oval metal plate with about 8 screws holding it in place. The memory is under the plate.

This forum is awesome and FAST. I'll go ahead and give that a shot. I'll post back later or tomorrow with that results. Thanks!

After removing the memory, I rebooted the printer. I was promptly faced with a 79 (0807) error.

I rebooted the printer twice more, and then I was able to print a normal, black & white document.

Would anyone think this printer is soon going to be more trouble than it's worth?

79 errors usually involve nothing more than rebooting the printer. Nothing to worry about unless they don't go away. I've seen millions of copies on that model. It's all in how you maintain it.
