2840 Memory Cards not recognized

Hi, my new HP CLJ2040 seems to work in all areas other than the memory card slots. I've tried Memory Stick and CF, and neither is recognized - nothing happens at all. Further, it shows up as 2830 in the HP Toolbox application, and I can't see any settings for the cards. When I push the photo button on the printer the display reads "not set up on PC". Any ideas what I can do?

Re: 2840 Memory Cards not recognized

Have you got it fixed yet ?

If not, are you quite handy with a Philips screwdriver ?

I have managed to fix mine by looking on the HP service forum under a post called "LJ 2840 seen as LJ 2830". Just g00gle it.

Have added my comments at the end of the post.

Good luck.

It wont read the cards

A: Make sure you're using a supported memory card. See the table below for specifications:

Memory Card Type Maximum Capacity CompactFlash Card
(Type I and Type II--3.3V only) 8GB Microdrive (3.3V only) 4GB SD (Secure Digital) 2GB MultiMediaCard 1GB

If you connect a compatible CompactFlash (CF) adapter that can read 8GB memory cards, you can also use the memory cards listed below (with a capacity up to 8GB):

  • Memory Stick
  • Memory Stick Duo
  • Memory Stick PRO
  • Memory Stick PRO Duo
  • xD-Picture Card
  • SmartMedia Card (3.3V only)

Have an HP L7680 all-in-one Just received a Panasonic Limuix camera and cannot read the SDHC memory cards in the SD slot - Printer posts an error

No, it's not possible, it'll never read SDHC in the SD slot. SD slot will only read SD, Mini SD (with adaptor) and Micro SD (with Adaptor). If there's no SDHC card slot, then it doesn't support SDHC Card. The lists of supported memory card are listed below:
CompactFlash™ Type I and II,
Secure Digital/MultiMediaCard/Secure MultiMediaCard (SD),
xD-Picture Card,
Sony Memory Stick®,
MagicGate Memory Stick,
Memory Stick Duo,
Memory Stick Pro

I hope this clears your doubt.

Note: SDHC and SD are different Memory Card types.

Good luck.

Thanks for using FixYa.

HP Color Laserjet 2840

There is only ONE SLOT for expansion memory for the HP 2840. The slot is located behind a cover on the right side of the machine looking from the front. Once you remove the cover you will see the one and only slot available for printer memory expansion. The slots on the front top corner ARE NOT for printer memory expansion but rather for different styles of photo/camera memory to off-load pictures etc...

If you need the printer memory cheaply (about $25.20 for 128MB) go to They have it in stock.

Hope that helps you. If so, please rate me with a FIXYA. :) If not give me a yell and I'll help you further.

How to install new ram into the 2840

Unplug the machine. On the right side of the machine you will find a cover. Remove the cover and you will find 1 open slot. The machine can take a total of 224MB (96 is built into the machine) leaving 128 available. The memory type is 100pin, 133MHz, SDRAM DIMM.

Simply click the memory into the blank slot and replace the cover.

Once completed, plug the machine back in and print a configuration page. The memory total should be at 224 once you have installed your 128MB.

Good Luck

Problem getting HP Photosmart to recognize digital camera memory card

From what read of the specs, the C6100 does not support SDHC cards, only SD cards. SD cards top out at 2GB; what you have is technically an SDHC (High Capacity) card, which does not work in SD devices.

Try using a different Memory card and see if it reads it, if not you might need to replace the memory card reader.
