Re: computer not in color printing mode

When you go to print, go to properties for the printer you would like to print. Once there find the tab that says color and make sure gray scale is checked off. It could depend though where that setting is at by printer. Please provide what printer you have. Just the brand no product number or anything only if what i gave at first does not help.

How do i turn on a compaq ps-7231 power supply?

Pin Name Color
Description 1 3.3V Orange +3.3 VDC 2 3.3V Orange +3.3 VDC 3 COM Black Ground 4 5V Red +5 VDC 5 COM Black Ground 6 5V Red +5 VDC 7 COM Black Ground 8 PWR_OK Gray Power Ok is a status signal generated by the power supply to notify the computer that the DC operating voltages are within the ranges required for proper computer operation (+5 VDC when power is Ok) 9 5VSB Purple +5 VDC Standby Voltage (max 10mA, max 2A in ATX 2.2 spec) 10 12V Yellow +12 VDC 11 12V Yellow +12 VDC 12 3.3V Orange +3.3 VDC 13 3.3V Orange +3.3 VDC. ATX V2.3 / EPS12V V2.92 both define that the PSU has to use remote sensing to compensate cable drops on the 3.3V line. Because of this there is an additional brown cable crimped together with the orange cable either to pin 13 (ATX) or pin 1 (EPS12V). 14 -12V Blue -12 VDC 15 COM Black Ground 16 /PS_ON Green Power Supply On (active low). Short this pin to GND to switch power supply ON, disconnect from GND to switch OFF. 17 COM Black Ground 18 COM Black Ground 19 COM Black Ground 20 -5V White -5 VDC (this is optional on newer ATX-2 supplies, it is for use with older AT class expansion cards and can be omitted on newer units) 21 +5V Red +5 VDC 22 +5V Red +5 VDC 23 +5V Red +5 VDC 24 COM Black Ground /PSON activated by pressing and releasing the power button while the power supply is in standby mode. Activating /PSON connects the power supply's /PSON input to ground, thereby switching the power supply to full-on condition.

Wiring scematic for a gateway gt5636e

Gateway Support > GT5636e Desktop PC > Main Support page,

Click on Components in the list.

Scroll down.
Under the black - Motherboards - subheading click on the blue -
4006245R - Intel (Stoughton) G965 motherboard with LPT port

In the list click on the blue - Product Views

B - Processor Core Power Connector
That is to the LEFT of the processor socket.

This is a general example of a 4-pin ATX +12 Volt power cable, and it's respective connector on the motherboard,

Note the LOCK clip on the power cable's connector, and the matching TAB, on the motherboard connector.
When the power cable is deemed to be plugged in Tightly, and Correctly; the Lock clip will be hooked over the Tab.

The 24-pin ATX main power cable's connector, and matching motherboard connector; has this feature also.

D - CPU Fan Connector
Go straight up, from the processor socket to the edge of the motherboard, then to the Right.

Notice how the motherboard connector is Keyed, and the matching plug connector that goes to it.
Same thing for all those white 3-pin connectors, on the motherboard.

[CPU = Central Processing Unit. Another term used is Microprocessor, or simply Processor for short.
Does NOT mean Personal Computer ]

G - Floppy Disk Drive Connector
Black 34-pin connector for a Floppy Drive.
It is next to the White 24-pin ATX main power cable connector.
Right side of motherboard, towards the Top.

If I were a betting man, I would bet you aren't using it. No Floppy Disk Drive.
But I'll tell you's nice to have.
A Floppy Disk Drive doesn't take squat to run.

Need to flash the BIOS after the BIOS has been corrupted, you can use a Floppy Disk/s with the BIOS upgrade info on it.
Jus sayin'.

H - ATX Power Connector = 24-pin ATX main power cable connector.
This is a general example of a 24-pin ATX power cable, and it's respective connector on the motherboard,

NOTE* Color of connector does NOT matter ]

Location covered above. Right upper side of motherboard

I - Rear Chassis Fan Connector

With the huge(?) image of the motherboard on Gateway Support, and the equally sized images available on the internet; you're on your own.

Easy to find though. Small white 3-pin connector, with Rear Fan printed next to it. I'm betting to the Left, of the aluminum finned Heatsink, for the Northbridge chip. (Below processor socket)

Next to an Electrolytic Capacitor, that has a gold, and black plastic sleeve.
Used for a computer case fan in the Rear. Draws air OUT of the computer case. (Out the back)

J - PCI Express x16 Connector.
THIS, is where the graphics card goes.
A PCI Express graphics card.

OR, you can use a PCI graphics card, in one of the white PCI slots.
I would NOT. The PCI technology is NO where near, the PCI Express technology,

The front of your computer is the Front Panel.
L - Front Panel Audio Connector, is for the audio ports in the Front Panel.

It is to the Left of the white PCI slots, and the header itself is Yellow in color.
Do not know the individual pinout of this Front Panel Audio header.

You have a plug connector that plugs onto it.
You can see the header is missing one pin. The missing pin is called the Key.
This shows you how to line up the plug connector to it.

If you need the individual pinout, trace the individual wires to the Front Panel audio ports.

N - HD Audio Link Connector
Plug connector goes on it also.
Location believed to be Bottom edge of motherboard, towards the Left.

O - Parallel ATA IDE Connector
Just the usual 40-pin IDE (PATA) connector.
(Actually, ONLY 39 pins )
Bottom edge of motherboard, black in color

ALL three harddrive options are SATA, so you won't be using it for your harddrive.
The optical drive you have is IDE (PATA), so this connector is where it plugs in.

Notice the cutout in the side of the connector. This is a Locating Notch.
Lines up with a Locating Lug, on the flat IDE ribbon cable, for the optical drive,

P - IEEE 1394 Connector
It's for the Firewire (1394a) ports in the Front Panel.
Plug connector goes to it.
Color is Blue, and it is in-between the white PCI slots

Q - USB 2.0 Connectors
Two of them side by side, but separated by a small Electrolytic Capacitor.
Black color for these USB headers.

They are for the Front Panel.
Location to the right of the black IEEE 1394 connector, bottom edge of motherboard.
They utilize the USB 2.0 technology.

ONLY one is marked. -> USB 2.
It has FP_USB_2, printed under it.
Front Panel USB 2.
The other one to the Left, is FP_USB_1.

EACH of those headers supports TWO USB ports.

A (Media) Card Reader has TWO cables, and uses ONE USB header.

One of those USB headers then, can be used for a Card Reader in the Front Panel.
The other USB header for Two USB ports in the Front Panel.

R - SATA Connectors
You see there are SIX.
Marking starts with SATA 0. (SATA0)

SATA 0 is for the SATA harddrive.
SATA 1 is for an optical drive (CD/DVD drive)

IF, you are using TWO optical drives, the MAIN optical drive connects to SATA1. The secondary optical drive connects to SATA2.

Make sure if you are adding a SATA optical drive, (That the computer did NOT come with), that you go into BIOS Setup; and ENABLE that SATA connector you wish to use.

HOWEVER,............the beauty of SATA is, that you can plug ANY device into ANY SATA connector; and BIOS will find the device.

Want to plug an optical drive into SATA0? No problem.
Want to plug the SATA harddrive into SATA 5?
No problem.

Just make SURE that SATA 5 is ENABLED, in BIOS Setup.

S - Front Panel Connector

Again, the front of your computer is the Front Panel.
Moving on.......
The area of contact pins on the motherboard, that the Main wires from the Front Panel connect to, is the Front Panel header.

Here you can see the individual pins, are marked by colors on the header itself.
Pin 2 is next to the Green pin, on the Bottom row to the Right.

Pin 1 is above it.
Looks confusing, because Pin 6 for the header above it, is marked right there also.

Pin 8 is marked on the bottom of the header.
Pin 9 is marked on the Top of the header, all the way to the left; except some 'crackhead' marked it upside down. (lol)


Starting on the Top row, at the Right side; going towards the Left,
Pins 1, 3, 5, 7, and 9.

Starting on the Bottom row, at the Right side; going towards the Left.
Pins 2, 4, 6, and 8. There is NO Pin 10.

1) Pins 1 and 3 are for the HarDDrive activity LED.
(Light Emitting Diode, so I'm not going to refer to it as a light.
It is. LED states that)

Pin 1 is for the Positive ( + ) connection.
If the HDD LED is dim when the harddrive is active, switch the wires around.

2) Pins 5 and 7 are for a Reset switch, IF a Reset switch is used.

3) Pin 9 is 5 Volts.
5 Volt power. That is why it is marked as +5 Volts.
Used for the factory to test with.
It is N/C. Not Connected.

4) Pins 2 and 4 are for a Power On LED.
Pin 2 is for the Positive ( + ) wire.
If the PWR LED is dim when the computer is on, switch the wires around.

5) Pins 6 and 8 are for the Power On switch.

6) Again, there is NO Pin 10.

T - Auxillary Front Panel Power On LED Connector
Right above the Front Panel header.

Freaking beats me why it would even be on there.
To iterate;

There are only 2 pins. This type of Power On LED header has 3-pins usually.
It is used for a dual color Power On LED.

Used back in the day when computers had the 'Turbo Mode' feature, and 'Normal Mode' feature.
Dual colors of dual color Power On LED was usually Green, and Yellow.
Green for Turbo Mode, Yellow for Normal Mode.

Was in reality a bunch of cr@p.
Turbo Mode was the computer actually operating in NORMAL mode, while Normal Mode was the computer was operating slower.
Just another gimmick.

{'Buy me! I'm a shinier Red bike! }

Probably why Gateway states it does Not support this feature.

U - Clear CMOS Jumper
If you do not know what this is for, LEAVE IT ALONE.
(He states politely)

V - Front Fan Connector
Yes, you guessed it. For the computer case fan in the Front, that draws air INTO the computer.
Location? Close to the round CMOS watch type battery.

X - Intrusion Switch Connector

Can't believe they are still using this cr@p.
It's so if someone opens the computer case, the power to the motherboard is turned off.

Good feature, but if the person working on the computer; doesn't know enough to unplug the computer from power FIRST, then chances are they do Not know about Anti-Static Procedures either.

Don't FOLLOW Anti-Static Procedures, you can use the motherboard for a Frisbee, or expensive paperweight.

Static shock the motherboard, is why.
Goodbye Processor (CPU), Ram Memory, motherboard, graphics card, (IF used)......and who knows what else.

DO NOT connect anything to it. Leave alone.

(If you do though, it has to be ENABLED in BIOS Setup; to use this feature)

Just put new color cartridges in and tested print and it showed all color bars however when i ask it to print it does not print out anything in black

You didn't say what brand/model of printer you are using, but a lot of printers nowadays have a color cartridge(s) and a separate black cartridge. Perhaps the black cartridge needs to be replaced, too?

Changing ink default to BLACK

Not possible.
Epson uses the black cartridge mostly, but also adds color to the black printing in order to keep the color inks from drying in the print jets on the printhead.
They also make lots of money that way...

Unfortuantely , to solve the issue , sadly, yes you will have to replace the empty cartridge to continue to use the printer in a normal fashion. Its a sneaky and dirty trick many printer manufactuers do to make more money off of the customer through the purchase of printer ink.

New Ink cartridges registering as empty ...

Is it an HP printer? We had the same problem at work with print cartridges purchased at Staples. They have a major quality control problem. Your new print cartridge may be empty or dried out (died on the shelf). It's my problem at work, as I have over 80 HP deskjets, and Purchasing still insists on buying the Staples cartridges rather than the HP.

Sometimes if you shake a print cartridge really hard it may correct the problem. However, I would buy or borrow a black HP print cartridge and try it out in your printer. Works almost every time on the job. Good luck.
