Roland SC-545EX pump assembly does not pumping

My Roland SC-545EX does not firing inks completely because the pump assembly does not pumping.

The pump assembly still working, but it doesn’t suck inks from the head.

Both of the 2 cupping connected to that pump assembly does not sucking inks.

I don’t have a budget yet for this part, is there any solution for this even if it just for temporary?

How to enter the service mode of Roland SC-545EX printer?

I want to do something in the service mode of my Roland SC-545EX but the problem is I don’t know to enter the service mode menu of the printer.

I know that after entering the service mode menu I can do the job next to it because it is a menu driven system.

All I need to do is just search for the function on the menu.

I know that expert on this site can give me the code.

How to remove Bubbles on the ink tube of Roland SC-545EX printer

I’ve a problem on my Roland SC-545EX printer ink. I found some bubbles inside the ink tube going to the dumper.

The dumper looks like empty because of the bubbles I found on the tube.

This is the reason why sometimes on my print out there are incomplete printing of color on the tarpaulin.

Please help.

My optical mouse stops moving and turns the mouse icon into busy icon

Please help me to fix my mouse.

The mouse pointer suddenly stops moving even if I am moving the mouse and then turns the mouse icon into busy icon.

I am experiencing this since last day.

I just thought that the computer is busy for something that’s why my mouse behaviors go like that.

But as time goes by, I also encountered more additional problem like I cannot right click.

Is this a virus or the hardware itself?

My monitor frequently turns on and off unexpectedly

I am in the middle of doing something in my computer when my computer monitor turns off unexpectedly.

Before I just think that it was caused by a fluctuating power in our area.

In the later time, the monitor turns-off frequently and I heard a little tick sound inside the monitor before turn on and off. 

My monitor is Samsung 17” CRT Monitor.

Image for tarpaulin prints the whole thing in pure solid black

One customer brings his image to us for tarpaulin printing.

I copied the image from his USB drive and sent it into your Roland SC-545EX printer.

I have got no idea why the image prints in solid black, no image was printed, and it was just a solid black.

What I did just to print the image is to re-make the whole image in Adobe Photoshop then save.

Anyone can explain how it happened?

Foam on my Roland SC-545EX waste dumper destroyed

I tried to replace the foam of my printer on the waste dumper (this is where the printer head blew inks before start printing on the tarpaulin) with ordinary foam, but the foam melts down when ink is dumped into it.

I try to replace it with URATEX foam but also melt. Our supplier doesn’t have that part, and they tell us that it is just ordinary foam.

I have got no help from them; maybe in this site you have the solution.

Greetings fellow TechyV members,

I have run out of options on how to solve my problem and I ask basically asked everywhere but still no luck in finding the perfect solution, so please inform me if this is the right place to ask this question.

I would like to inform you first hand the specifications of my system. I have a Packard Bell, 1.66 ghz processor, 2gb ram, running on Windows Vista. It can run games like Doom 3 and Fallout 3 pretty fairly. But I have this annoying problem while playing games. There is an occasional brief lag and slow downs (the screen refreshes about 20-25 fps) while I am playing, after that it returns to normal and after 2-3 minutes the lag starts again.

I recently got a 5.1 surround sound home entertainment set and tried to connect it to my computer. 

When I plugged it in via a Cable Jack it only brings out the sound of 2 speakers. The others are just making a noise like bad feedback.

I also installed RealTek Audio manager as my sound driver. But it still doesn't work.

What can I do?

I have a problem with my keyboard on my laptop.

Whenever I press the letter "A, C, W" the A comes with a S and the C with an X and a W with a Q.

I tried to clean up my keyboard, but it still has the same effect on it.

Is there something I can do to fix this?
