printer light is on but printer won't warm up

"Hi,

This is just a general check list, applicable to a lot of laser printers.

1. Remove the power cord.

2. Open the front cover and remove and reinsert the cartridges.

3. Before you close the front cover, (not quite sure if this is applicable to your model or not) check to see if there is any kind of 'safety switch ', which would be operated by the cover being closed. If there is it may be that it has become dislodged or disconnected.

4. Ensure that the front cover is closed securely.

5. Reconnect the power cord and switch on the printer."

"I have the same problem. The lights come on but it does not get recognized by the computer and it doesn't go into the warm up cycle. The blue light around the power button is on and this is supposed to indicate that it is in Standby Mode. The blue light doesn't light up on a successful start up. The only way to shut it down is to pull the power cord. After pulling the cord I hold the power button down to dissipate all the residual power in the printer and then plug it back in and try powering it up again. I may have to do this 3 or 4 times before I finally hear a little click and then it goes into the warm up cycle. I wait a few minutes after hitting the power button to give it time to be recognized by the computer. Sometimes it will actually power up on the first attempt. Have tried a different power cord and a different USB cable and still have the same problem.

I've tried doing firmware updates and have run the Samsung Printer Diagnostics with no luck.

The printer is over a year old but I don't print very much. It has a print count of less than 400."

"Still trying to make this non warming up printer work. But so far no luck.

Did find a site http://www.instructables.com/id/Samsung-... that reports a lot of success. Apparently if you can reset a counter with a resistor, your printer will work again. Reports are that it works on many Samsung printers including C410W.

I'm still looking, gary"

"I’m attaching (I hope) a photo of the board that is the problem component of many Samsung Xpress C410W color laser printers.

If you look toward the center left of the board you will see a chip labelled ‘SAMSUNG ARM’ and that is the “brains” of the electronics of the printer. Considering semiconductor components either work as they are designed to or they don’t (there is no half functional or whatever) it is unlikely that this is an issue of a defective chip because that would create printers dead at first attempted use. As well, considering that when this printer fails as badly as I (and obviously many others) have experienced it must be a very critical component and so ARM chip (an ‘SoC’, System On a Chip) is the most likely culprit. Those ARMs (as is obvious in the photo) are electrically connected (soldered) entirely by many small, ball shaped contacts on their bottom, and although I cannot easily find the specifics of that chip there are probably a large number of contacts underneath that chip. Properly installing those BGA (ball grid array) chips on electronic boards is, as you can imagine, a tricky and challenging job. Industrially the work is done by machine of course but obviously it very difficult to truly verify that they are all done perfectly. I predict that one or more contacts under the ARM were poorly soldered and with movement of the board (as the printer gets moved or transported) plus temperature and even moisture fluctuations where the printer is or has been results in the poor connection(s) finally opening and the result is a dead, “bricked”, printer.

"The Power button does not appear to be damaged. I've tried plugging the printer in in another room (by itself, no computer) and still nothing. I've also left it unplugged overnight and even tried using a different power cord. It just will not power on. Note, the printer was working just fine yesterday afternoon. The only thing I did was turn it off in mid-operation.

Even if the power button were damaged (and I see no sign that it is), it should turn on by itself when I go to print. Instead, I get an error message simply saying ""the printer is not ready."" (at first, I was getting a message that ""the printer is offline"", but I was able to toggle that by going into the Printer Properties in Windows and changing its online status.)

The printer is only slightly over a year old, so it's no longer under warranty (naturally). Newer models are junk, so even though Canon has a ""trade-in"" program, I'd rather fix this one (which SHOULD be something simple).

I bought the ""Canadian"" version of this discontinued printer specifically for it's CD printing capabilities. Newer models... and ALL U.S. printers... disable this feature (by law?) According to Canon (after I asked), there is no fuse inside the unit that might have blown."

nothing is solved, still a mystery. my printer has a blue light but button is unresponsive to touch.
