All LEDs are blinking means the head cannot move freely. Clean the iron rod that head moves.

SOURCE: Epson LQ-590 Matrix Printer Paper feed Problem

Assuming that you are feeding the paper into the correct end of the printer :), it seems that the printer is defective, but

First unplug the printer from the wall, wait a few minutes,
and see if it resets. If that does not work, read on.

  1. Printer rollers (and sometimes head movements as well)
    are controlled by "Stepping Motors"

    Unlike an ordinary DC motor with two wires, that spins
    clockwise or counter clockwise depending on the voltage
    polarity,

    a stepping motor contains several pairs of wires, that
    are pulsed in a controlled sequence, causing the motor
    to spin in precise angular steps. Depending on the
    number of wire pairs (poles) and internal gears, the
    stepping motor can have a resolution as course as
    90 degrees, and as fine as 0.05 degrees per step,
    depending on the cost and applications.

    Linear stepping motors can even move an object in
    a straight line.

    The benefit of these stepping motors is that, unlike a
    linear servo motor, they do not need complex positional
    feed-back for precise control, they simply step as many
    times as you tell them to. Four steps left, two steps back
    .... etc.

  2. These stepping motors are in turn driven by semiconductor switches (transistors) which are
    ultimately controlled by a central processor within the printer.

    Depending on the printer model, and how sophisticated
    the printer's internal processor is, the paper and head
    movements can be either automatically controlled by
    SOFTWARE (firmware) within the printer itself, or by the device drivers installed in Windows.

    The more self-sufficient the printer is, of course, the less
    hassle and CPU overhead on your PC.

  3. When any of the components within this chain of command fail, the stepping motor will move incorrectly:

    a) Skip steps
    b) Get stuck
    c) Oscillate back and forth
    d) Spin backwards.

  4. The causes could be:

    a) One bad wire in the ribbon connecting the motor
    to its controller board.

    b) Bad motor driver transistor: Open or shorted.

    c) Bad data line from the printer's internal control
    processor to the driver transistor array.

    d) Bad processor chip, memory or firmware within
    the printer, e.g. a burned out register or firmware
    memory location.

    e) Defective internal power supply, causing everything
    else to malfunction.

    f) Bad paper position sensor

    d) Crashed control program, which is probably the
    only thing that is fixable:

    i) unplug the printer from the wall socket, wait a
    few minutes, and see if it resets.

  5. It is also remotely (theoretically) possible, that
    the Window drivers are corrupt but this is very unlikely.

  6. If you are fairly brave and want to take the printer apart, and have some electronics knowledge and a few basic instruments, probe the roller drive motor wires, and see what gives. Is one wire stuck consistently low or high ?

    Is one of the motor windings open or shorted ?

    Is one of the driver transistors fried ?

    This very much depends on your level of skill, and the test equipment you have to work with. If you don't have a decent oscilloscope you will not get far. Without a digital multimeter you will not get anywhere at all.
Also do not forget that printers are dirt cheap, less than the ink when it runs out, so this may not be worth your time and effort.

Call the manufacturer, scream blue murder, accuse them of setting your house on fire and giving your dog diarrhea ....

and see if they will send you a freebee.

Hope this explains it.
Please rate my answers.

SOURCE: My Epson LQ-590/LQ-2090 keeps having paper jams

When a paper jam occurs during printing for some reason, the printer beeps, displaying the message <PAPER JAM> in the display. When a paper jam occurs, remove the jammed paper using the following procedure, and then resume the job. If the message that indicates the paper jam does not disappear even after removing the jammed paper following the procedure, there is a possibility that torn pieces of paper are still left inside the printer. Inspect each part of the printer again, and completely remove all pieces of jammed paper.

Laptop LED Blink on Startup
There are many reasons that a computer does not startup or boot into the Windows operating system. If your computer will not start or boot, you will see or hear symptom to indicate the general area of the problem.
Startup Symptom: LEDs blink but does not start
The blinking LED lights on newer computers, or the beep tones on older computers, will help support agent determine what hardware component is not responding properly. The exact meaning of each code varies with the model, and the user cannot change any of the blink or beep codes.
DO THESE FIRST - Perform a hard reset.
If a PC suddenly fails to boot properly, you should perform a hard reset as the first procedure.
1. Disconnect all peripheral devices and remove all USB devices and media cards. You want to test the computer not the accessories!
2. Disconnect the AC power adapter, remove the battery and then press and hold the power button for at least 15 seconds.
3. Reconnect the AC power adapter (but do not connect the battery), Press the Power button, Look for glowing LEDs near caps lock and num lock keys, and Listen for sounds of a disk drive and fan turning.
Identify the number of blinks or beeps
When there is a start-up problem and you see LED lights on the keyboard blink a few times (between 1 and 8 blinks) do the following actions.
Table of Sample Blink Codes
The following table illustrates the meaning of blink codes used on some notebooks. The blink or beep codes on your computer may have different meanings.
Meaning of Sample Blink Codes for some EFI Notebooks:
1) Number of Blink: Continuous Glow, Blinking LED: Battery power LED, Component: Battery,
Error Condition: The AC adapter is attached and the battery is charging, but does not yet have sufficient charge to power the notebook.
2) Number of Blink: 1, Blinking LED: Caps Lock/Num Lock, Component: CPU,
Error Condition: CPU not functional
3) Number of Blink: 2, Blinking LED: Caps Lock/Num Lock, Component: BIOS,
Error Condition: BIOS corruption failure
4) Number of Blink: 3, Blinking LED: Caps Lock/Num Lock, Component: Memory,
Error Condition: Module error not functional
5) Number of Blink: 4, Blinking LED: Caps Lock/Num Lock, Component: Graphics,
Error Condition: Graphics controller not functional.
6) Number of Blink: 5, Blinking LED: Caps Lock/Num Lock, Component: system board,
Error Condition: General system board failure.
7) Number of Blink: 6, Blinking LED: Caps Lock/Num Lock, Component: BIOS,
Error Condition: BIOS authentication failure.
8) Number of Blink: Continuous blink, Blinking LED: AC power adapter LED, Component: Power adapter,
Error Condition: Insufficient power
Common solutions for issues that cause blinking LEDs or beep tones
When the computer can boot into the BIOS, run the memory test to identify other issues.
Check for loose connections and test the memory
Blink codes are often displayed after a user adds memory to the computer but does not seat the module properly. The LEDs may also blink error codes if a hardware component is loose because the computer was dropped or jarred. The problem could be that the stick of memory or one of the memory slots has a bad connection.
Check for loose memory modules
If a memory module is loose or is not making good contact with the memory slots, the computer does not recognize all of the memory. Reseating the memory module may resolve memory failure errors.

My Frigidaire GLFT294OES3 turns on, but after a few seconds, it goes to "No Spin" and errors out. The water won't come through and it just shuts off, please help!!!


To recall an error code,


Wake the machine by pressing any button


Wait 5 seconds


Press and hold the Start and Pause Cancel buttons simultaneously


Ail LEDs will go blank and after a few seconds the control will signal the stored code using audible beeps and blinking LEDs. The control will repeatedly signal the code, as long as the Start and Pause Cancel buttons are pressed.


A two-second pause between repeats affords you the ability to make accurate counts to identify the correct error codes.


You may also have a code such as E47 or E24 etc..

Comme back with the code and I will explain what is the meaning of the code

On My Dv5-1125nr both the caps lock and num lock keeps blinking when i turn it on. It's wont boot at all. What kind of hardware problem is this?


First remove the battery and power cord for about a minute. Then plug back in and see if that helps. Otherwise please read the following:

LEDs near Caps Lock and Number Lock keys blink when starting notebook The LED lights near the Caps Lock and Num Lock keys will blink if an error is detected during the start up process. The LEDs will blink a number of times in a sequence and then stop. The number of blinks in the sequence indicates what component caused an error when it was being tested during start up. If the LEDs stop blinking and the computer does not start, you can press the power button again to repeat the tests. Count the number of blinks, and use the chart to identify the error condition. Knowing the number of blinks is helpful when you contact an HP support agent for technical help. Caps Lock/Num Lock LED Component Tested Error Condition LEDs blink 1 time CPU CPU not functional LEDs blink 2 times BIOS BIOS corruption failure LEDs blink 3 times Memory Module error not functional LEDs blink 4 times Graphics Graphics controller not functional LEDs blink 5 times System board General system board failure LEDs blink 6 times BIOS BIOS authentication failure

The front LED flashes red & blue when I turn it on. What does this mean?


LED Indicators - LaCie 2big Network
The LED indicators above the drive bays and the front LED indicate drive status and activity.
During Startup
  • Front LED – blinks red/blue until both disks are powered on, then turns solid blue.
  • Rear LEDs – blinks red/blue until corresponding disk is powered on, then turns solid blue.
NOTE: If the device is not able to initiate the boot process following disk startup, the front is solid red.
During Bootup
  • Front LED – solid blue
  • Rear LEDs – solid blue
NOTE: If a disk is failing, both the disk’s corresponding rear LED and the front LED will be solid red.
During RAID Synchronization
  • Front LED – solid red
  • Rear LEDs – The LED corresponding to the original disk will be blinking blue and the one being synchronized is blinking red
  • Once both disks are synchronized, their corresponding rear LED and the front LED will be solid blue.
