50 service flashing on display screen

Will not allow me to print

  • DennisC2 Jan 15, 2009

    I am having the same problem. I ordered a new fuser assembly, put it in and am still getting the "50 service" error. The printer had been off for several weeks when I replaced the fuser assembly. Any other ideas, or is it time to buy a new printer?

    Thanks

If the display panel reads 50 FUSER ERROR, CYCLE POWER, turn the printer off for 15 minutes. This allows the capacitor that is responsible for signaling this error to discharge. If you don't wait 15 minutes you will continue to get this error even if you have replaced the fuser. If it continues to show the error, then you need to replace the fuser. It is easy to replace.
The fuser maintenance kit is about $119. on the web.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

My display has the wrench icon and the time icon and it says "OFF" on the display on the dash. What does this mean? and how do i get it off?


Programmable service interval
The purpose of the programmable service interval is to provide the consumer and dealer with a convenient reminder for routine maintenance. When your vehicle leaves the factory, this feature is set at 50 hours. You must enable the programmable service interval before it
can be used.
Once the service interval mode is set with the hours when service is due, the hours of actual engine operation are subtracted from the set
hours until 0 is reached. When the counter reaches 0, the wrench icon will flash quickly for 5 seconds each time the vehicle is started as a reminder that the periodic maintenance is due.
To set the hours, press and hold the mode/override button until the wrench icon flashes. When it begins to flash, release the button. The setting will increase by one hour each time the button is pressed.
Pressing and holding the button will allow the numbers to escalate much faster. When the desired time increment is displayed, release the button and wait for the wrench to stop flashing. When the wrench stops blinking, your service hours are set.
NOTE: If you scroll past the intended number, hold the button down until the count turns over to 0. You can then reset the number.
If the service interval is enabled on your ATV and you wish to turn it off, toggle to the service interval mode. Press and hold the mode button for approximately 7 seconds until the word OFF appears in the
Rider Information Center.

Brother 540cn Printer won't print and displays unable to print 50. The photo capture button also flashes


The error code 50 indicates a paper jam condition. Whether there's actually still paper jammed or not, it's sensors are still indicating a jam. Check again for a bit of paper, or there may be a faulty sensor.

How do i reset the change oil light on a 1040 cub cadet 1000 series


The Service Monitor meter contains a service minder function that utilizes the 4-digit LCD display. The letters "CHG" will display followed by the letters "OIL" and then followed by the meter accumulated time. "CHG"/"OIL"/TIME will alternate on the display for five(5) minutes after the meter reaches 50 hours. The display will also flash as described above for five(5) minutes every time the tractor has been started during the maintenance time interval. The interval will occur every 50 hours and will be in effect for two(2) hours ( Example: this feature will display from 50-52 hrs., 100-102 hrs., 150-152 hrs etc...). While the LCD is displaying the "CHG"/"OIL"/TIME letters, the red LED "oil symbol" will also be flashing for the entire five(5) minutes. The meter display will return to normal function automatically after the reminder maintenance time interval of two(2) hours.There is no method of manually re-setting this Service Monitor gauge.

My pixma ip8500 is printing with some colour missing, all cartridges have ink in them?


Hi there,

When Printing Becomes Faint or Colors are Incorrect.
When printing becomes faint or colors are incorrect even if the ink remains in the ink tanks, the print head nozzles are probably clogged. Print the nozzle check pattern to confirm the condition of the nozzles and then perform the Print Head Cleaning.
Note : Before performing maintenace

*Open the Scanning Unit (Printer Cover) and make sure that all lamps for the ink tanks are lit red.
-If any one of the lamps is flashing slowly, the associated ink tank is running low. You can continue printing for a while, but we recommend you to have replacement ink tank available.
-If any one of the lamps is flashing fast, the associated ink tank is emty. Replace the ink tank.
If an ink tank is flashing fast even though ink remains in that ink tank, it is inserted into the wrong position. Make sure that the ink tank of the correct coloris inserted in each position matching the label.
-If the ink lamp is not lit, the tank is not set properly. Press the <PUSH> mark on the ink tank until the tank clicks into place. Make sure that all the packaging material is peeled off the ink tank.

Thanks.
Have a good day.

How do you print at 50% w/ an 5610 all in one


I am taking you literally in as much as you did not say "copy at 50%" which is done through the 5610's front control panel.

To print at 50% you use the browser printer settings.

Firefox:
1. Go the the "File" drop down (upper left)
2. Go down to the "Print Preview" selection... a preview screen will then be displayed.
3. Look to the top right part of the screen to find the "Scale" field and set this to 50%. The page will repaint to show you the new print size.
5. Hit print

Internet Explorer:
1. Go the the "File" drop down (upper left)
2. Go down to the "Print Preview" selection... a preview screen will then be displayed.
3. Look along the top-right of the screen for a drop-down field that may say "Shrink to Fit" or a percentage. click this and set it to 50%. The page will repaint with your new setting.
4. Hit the printer icon in the upper left to print.

Hope this helps. Best of luck - Dan
