Hi, when your PC boots up and you see the memory test, and drives listed, you need to enter the BIOS setup.

Pushing the "DELETE" button will usually do it, if not it may be the F2 button. It will say on the screen what button to push.

Once in the BIOS you need to look through the listed items untill you find the parrallel port settings ( I can't be more specific as all BIOS menus are slightly different) you should have instructions as to how to change and save settings on screen.

Hope that is of some help

My computer cannot detect my scanner. Error Code: 0x0070800

The FB320P is a parallel port scanner and is having problems communicating with the computer. Are you connecting it directly to the parallel port on the computer? In that case, you may not have bi-directional communication enabled. Turn off the scanner and the computer and disconnect the data cable from the computer. Turn on the computer and enter the BIOS. (Press Esc, F1, F10, or Del repeatedly after you turn the computer. You should see a screen with the correct key to press; it varies depending on your BIOS and motherboard. If you miss the timing, shut down the computer and try again.) In the BIOS, search for the parallel port settings and see if you can enable bi-directional communication.

Not all parallel ports support bi-directional communication. If you can't enable the feature, you need a different parallel port. Try a PCI slot add-on card; just check the features and check the manual for enabling bi-directional communication.

If you are using a USB to parallel port adapter, get a different one that supports the bi-directional communication.

What OS are you using? There are a few that had ASPI driver issues; a third party app, ForceASPI, may help. See for information.

I hope this helps. Please add more information about the configuration (cable, OS, etc) for extra ideas to solve the problem.

Error badint 0085ddc0

The 'badint' error on the T6100 indicates the printers firmware has for some reason 'crashed', this error should not be seen in normal operation of the printer.
One common cause of "BADINT" messages is the use of an external print server or host computer with incompatible parallel-port settings. If you have an external print server connected to the printer's parallel port there is a setting on the print parallel interface that may need changing, to change parallel interface setting. • Set the printer to Offline. • Press the Enter and LF keys together for approx 3 - 4 seconds. The alarm will sound. (Tech Access On) • Press the Mode key: display will show Offline Normal. • Press any Arrow key until display shows Offline Config. • Press the Forms/1 key. • Press any Arrow key until display shows Config Paralel. • Press the CPI/2 key. • Press any Arrow key until display shows Paralel Bi-Dir. • Press the LPI/3 key. • Press any Arrow key until display shows Bi-Dir Off. • Press the Enter key and the interface will be set. • Press the Clear key. • Press the Enter and LF keys together for approx 3 - 4 seconds. The alarm will sound. (Tech Access Off) On the external Print Server, you need to ensure that the unit is also set for Uni-directional working.

I receive a "Cannot connect to PC" when I try to scan using my HP OfficeJet T45xi printer/fax/scanner/copier using Windows XP Home Edition with SP3 on my Dell Inspiron 600M. I have downloaded and run the...

That is the correct driver.

Make sure you have a good cable (with bidirectional support). Check that the ECP mode is enabled for the parallel port in the Device Manager. Click Start > Properties (Control Panel). Click on the Hardware and then the Device Manager. Open the Ports section and look for the parallel port option (LPT1). Double click on this and look at the Resources tab. If the printer is connected in ECP mode, you will see two entries for the I/O ranges. This may need to be enabled in the BIOS (often reached by hitting F1 or F2 when restarting the computer before the OS loads). If you adjust the BIOS setting for the port, you will need to return to the Device Manager and adjust the Port Settings to Enable Legacy Plug and Play.

If you use a USB to parallel adapter, make sure you got one that supports bi-directional communication.

I hope this helps.

Cannot communicate with printer. Told to Turn

Restart your computer.
Press <DEL> to enter BIOS SETUP.
Find the setup-screen that changes the mode of the printer (PP/"Parallel Port" or EPP/"Extended Parallel Port", or ECP/"Enhanced Port"). Select EPP or ECP.
Then, 'SAVE' the updated BIOS settings,
and exit from BIOS SETUP.
Restart your computer.
The box will _not_ be "grey".

I have a BJC80 printern with a scanner head. My pc is an xp opertins system. It is connect to parallel port but when i try to scan, it sends me back an error message saying there is no communication.

One of two issues may be involved. 1) Make sure you have a bi-directional IEEE-1284 parallel printer cable, 6 feet or less long. 2) Make sure that the parallel port is set to ECP mode (the BIOS is accessed by hitting F1 or F2 during boot on many computer, check your manual.) Try a new cable (just in case the cable has just enough damage to prevent the scanner from getting the full bi-directional communication).

I hope this helps.

(the lack of bi-directional communication only disables the scanner, the printer will still work)

Lexmark 3500-4500, enable bidirection printer

Bi-directional operation is a facility of the BIOS port you might use. it usually refers to a parallel port which can be set in the bios as uni directional or bidirectional so in the bios under PERIPHERAL DEVICES you would set to bi-directional.. so it is not something you can set in the printer settings. when it connects to the port the printer tests to see if it can use bidirectional transfers or not. If it can't it just means its a bit less efficient so will take long to transfer data. A similar error message might be issued for a network/wifi connection if a FIREWALL prevented communications. Or if you had used an OLD driver meant for a different older parallel printer. your printer is too new and should be wifi connected. You may have used a wifi ad-hoc pc-printer direct connection which could be causing the issue. preferred method is always printer-router-pc non ad-hoc using tcp/ip ports. so check your firewall settings

BJC 80 w/ Vista OS prints 1/2 page and goes to error mode.

Purchase a PCMCIA parallel port card. That's a PC Card parallel port adapter. It provides a native parallel port to laptops that do not have one built in. Works perfectly in ALL cases, even with the scanner cartridge.

Here is the link to the user manual in french; or here in english; The solution to the unidirectional issue depends if you have the printer connected in parallel or by USB. In USB connection the printer can be set to bi-directional mode in the "ports" tab of the printer properties, assuming that the USB is setup correctly. In parallel mode this option is not available to change. On some other HP models, there are a bank of DIP switches inside that allow uni/bi-directional switching, but i found no info detailing these for this model, so i suspect it is only possible with the software. Hope this helps :)

Internal error 11

Is your printer connected directly to your PC? I?ve found some literature that suggests this is or is related to a communications problem. I would suggest removing the printer and reinstalling it from scratch. If you run into problems try another cable, remove all other USB devices (if you?re using USB to connect the printer) or if using a parallel cable switch your parallel port to ECP or bi-directional printing mode. Let us know if this helps and please don?t forget to rate this post.
