Why won't my HP F340 all-in-one printer print photos in color, only B&W. The test page does print in color however


Make sure you are selecting color. Mine will do either way. There should be a selection on how you want it.

It is the powertype plugs that plug into the mains circuit not my router flashing but now both plugs are showing green but youview box not responding


I am sure you have tried this, but if not give it a go:-


Switch off both powerplugs and leave for 5 minutes..

Switch on the powerplug nearest the router without the LAN cable installed.

Wait for 2 minutes and switch on the other powerplug without the LAN cable being attached.

Now wait for another 2 minutes before plugging in the LAN cable

Now plug in the LAN cable at the router end.

After about 2 minutes, plug in the LAN cable at the remote end.

Good luck.

Red light start button


the problem may be the scanner are you able to scan to pc or email/fax from the machine glass/
when the machine initializes are there any faults displayed ( the printer will continue to function even if the scanner fails) usually the error code 30.01.02 or something like that will be displayed-
the scanner is connected via 1 large connector found to the rear of the machine - does the cable look damaged in any way- is the connection 'good' has the grounding wire worked loose, if after these have been checked there is still no scanner then you may need either a scanner or main PCA/formatter fot the printer.
Belmonte business are able to help with the repair of this unit should it be required and would be subject to the usual costs.

I have epson stylus photo 820 inkjet printer with no cables or electrical wire to plug it in. I do have the software CD. What specifically do I need? Looks like the "parallel" insert would...


This printer uses a "parallel-port" cable to connect from the printer to your computer.

See: http://www.cable-trader.co.uk/images/items/Bi-directional%20parallel%20printer%20cable.jpg
for a picture of the required "data" cable.

This printer also uses an external power-supply (a "brick" and a cord).
Look on eBay to find an inexpensive, compatible, unit.

It might be cheaper to buy a brand-new printer.

I have the bd230 5.1 system hooked up the speakers, attached the power cord and hdmi cable from receiver to the tv what else do I need to get sound from my tv I have a hd cable.box do I need to run a cable...


The home theater box performs the production of the sound generation. Also, the theater box, distributes the sound to any display devices like TVs, Music MIxers, DVDR, VCRs, ext. The theater box also has connection ports that are recognisable as receptacle area from speakers, woofers, and twitters that combined to form the home theater of devices acquired. First, start by connecting the component parts of the theater system to the box. For example, speakers to an area on the box, twitters, woofers. At which point, the box would require a power cable to an electrican circuit to display functionality mode. The next step is deciding on which display reciver would be providing sound to the theater setup of blasters. For example, choosing to acquire sound from a TV set is achieved by connection cables that derived sound out of the TV to the theater box. E.G. The TV audio output area provides the connectivity of any external audio blasters like with the theater setup. Using the appropiate audio input output connection cables to acquire sound transfer matters. The device may not have been provided with a TV audio input out cable of connections. Acquire from retail input output cables from TV to theater boxes. Remember that, the theater box may have come with a remote control that require separe operations than the TV. The theater system theraafter would require power on buttons if any separate remote controls were acquired as well. Also, the television set would require alteration settings with the remote control. Adjusting the TV sound settings to acquire or direct internal sound to an external setup infrusture is possible explanation also achievable with TV REMOte controller soon after every wireing cables have been established alos powered on to source of current.

I have an 03 Kia Sedona 2.4 auto. The battery was flat but is being charged by a mechanic. For some reason the imobiliser alarm keeps going off and we can't disarm it using the key fob, any ideas? The car...


The errratic fault of the unit and the draining of the battery requires that this unit be replaced if the main unit cannot be repaired by the dealer. You can alos have a power switch in place so that it can be deactivated when ever required.
Since this wont reset the unit motherboard has errors and so in the long run it will only cause issues with such erractic switching.

Hp7410 Wont turn on and function, power light doesnt come on and the HP Invent Logo keeps cycling on and off

How can i hook up my printer to my computer


Most printers either have at least one of:
* parallel-connector, requiring a "parallel-printer" cable,
* a USB-connector, requiring a "USB-printer" cable.

So, connect the correct cable to your printer,
and connect the other end to a "parallel" or "USB" connector on your computer.
