Too much feedback


Can you explain your terminology? Feedback or Standing Waves? Typically, Feedback is audio feedback through the speaker and back into the microphone of the CB or out of the external speaker into the mic. It can also be RF Feedback that is caused when the system. If it is audio feedback, it could be that someone has installed a T
"talk back" option and that's why you are getting feedback, if it's audio feedback.

My matrix MX-T5x start running and stop in seconds. With the error code E7. What is the problem ?


Hi,
By E7 it means Speed sensor feedback missing. You have to check the speed sensor mounted near the motor pully. Remove the speed sensor and clean it well Then refix it then check the tread mill by powering ON. If then also the problem remains the same , You have to replace the speed sensor.
ok

Ihave sharp Ar - 287 printer the problem in it appear this message call for service . code : E7-11


E7-11 = Shading Trouble

As part of it's calibration process the copier measures the light given off from the copy lamp by its reflection from a white strip under the glass. If the copy lamp has failed this will also give this code.

With the power off and the machine unplugged try cleaning the mirrors and the white strip under the glass. It is sometimes possible to fit the glass upside down so it's worth checking that the white strip is facing down.

This code will normally reset by powering off/on.

Hope this helps

Hi my copier displays E7


Check this out :
E7 codes deal with the optical scanner unit and or the laser unit. It could also be the lamp in the scanner unit. The E7 is the main code. There is a sub code associated with it. To view the sub code hold down the start button. Below is a list of specific codes and their meanings:
E7-02: LSU trouble
E7-10: Shading trouble (Black Correction)
E7-11: Shading trouble (White Correction)
E7-12: Shading Trouble
E7-16: Abnormal laser output
If it is a laser (LSU) issue then the LSU may need replacing.
If it is a shading error the first step is to remove the platen glass carefully (with the power off because the inverter board). There is a thin white strip on the bottom side of the platen next to the **** glass. Clean this white strip with a soft cloth and a small amout of isopropyl alcohol.
Dust on the optics can also cause shading reference errors so gently blow off the mirrors with canned air.
Perform the following key procedure to reset error:
"#" key, Interrupt key, "C" key, Interrupt key
"1" key, "4"key
Start key, "CA" key.
See if unit cycles and comes back up. If not turn off and then back on the main power.
If error reappears on site technical service may be required.
