Q. What’s the quality assurance period for G&G toner cartridge?

-
A. 24months.

Q. Will the environment factor affect the printing quality of compatible toner cartridges?

-
A. The best storing temperature for cartridges to obtain best printing quality is 10- 33 centigrade, 20-80% humidity. If storing in high or low temperature/humidity for long time the printing performance will definitely affect.

Q. Will compatible laser toner cartridges damage my machine?

-
A. No, and we guarantee it. Your printer, fax or copier should produce quality print jobs with either new or remanufactured toner cartridges. If your machine does break down and the repair proves to be cartridge related, our customer dept. will check and offer credit for repairing the machine.

Q. Do remanufactured toner cartridges last as long as new?

-
A. Yes. All of our toner cartridges are filled to maximum capacity and are carefully weighed before distribution.

Q .Installation failed

-
A. a. Please check whether the protection shield is removed or not open. b. for some models, we produce universal version or patent version, the structure will have small difference from original, it may have some interference during installation, pls try more times to install or follow the instruction on cartridge or in box. c. for Brother toner cartridge, there is technical gear on one side. Because each cartridge is tested on assembly line, sometimes after test the worker may forget to reset the gear which causes failed installation. But we have used fool-proofing design, this case happen rarely.

Q. Cartridge can’t be recognized

-
A. a. take the cartridge out from the printer, check the cartridge chip and the contact point in printer, use a dry cloth or paper tissue to clean the chip and the contact point if necessary and then reinstall. b.If the cartridge is without chip, please check whether the technical gear is installed properly, and reset it by following the instruction on our website c. For some brand for example Samsung/Lexmark, the original manufacturer frequently update the hardware, old chip can’t work on updated version, pls contact with your sales manager for a new updated chip. d. Please check the compatibility list if the cartridge can be used for this printer. Sometimes XXX capacity cartridge can’t work on printers which use lower capacity. e OEM has more and more complicated chip technology, to avoid the aftermarket competition, for some Lexmark and HP new models, the aftermarket chip has many serial numbers. If you use same serial number chip on same printer, the printer will report error code. You need to replace with a new chip or another cartridge.

Q. Chip of compatible Samsung toner cartridge cannot be recognized

-
A. a. .Say "NO "to firmware upgrade of Samsung series printer b. As you know, Samsung typically suggests firmware upgrades but this will most likely have an effect on the cartridge chip. Please keep in mind that your printer should not be upgraded if you want to continue using the compatible cartridges. If you prefer an upgrade, please consult with your sales manager or G&G customer service for assistance.

Q. Lower Page Yield

-
A. a. If the page yield of compatible carts is within 5% less than OEM’s, this is normal as page yield is not just depended on how many toner is filled, but also affected by the state of printer/ environment/what you print/prints coverage/concentration setting etc. b. If the page yield of compatible carts is less than OEM’s dramatically (more than 5%), there may be several reasons. 1. The filled toner is not enough. Usually this will happen rarely, because we have strict quality control, for each batch we randomly inspect the quality and weigh it, if the difference is big, we will find it before delivery. 2. The document customer print is with high coverage. High coverage printing will cost more toner than for each page. OEM and aftermarket producer use ISO19752 and ISO24712 standard to test page yield, the coverage is 5%. As most users print more graphics, gray scales and large amounts of text which with high coverage, obviously the page yield will not be enough.

Q. If you get blank print out

-
A. . a. please check whether the sealing tape is pulled out if the blank printput is printed b. If the laser door inside the printer does not open, the laser bean cannot reach the OPC then there will no discharge on OPC thus no toner powder will be transferred. A broken OPC shutter door will stop image to be transferred from the OPC to the paper.

Q. If you get black printout

-
A Failed conduction may cause black printout, please check the conductor on both side of the cartridge, please clamp the conductor and reinstall

Q. Periodic lines or points on printout

-
A. Extraneous impurity may cause periodic lines or points on the output, please place the cartridge with the opening section downward to make the extraneous impurity drops out

Q. Paper Jam

-
A. Please follow the steps below to solve the problem, NOTE: Illustrations shown below are for representative product and may differ from your machine. 1 .Open the front cover. 2. Leave the machine turned on for 10 minutes to cool down. 3. Slowly take out the drum unit and toner cartridge separately. The jammed paper may be pulled out during taking out drum unit and toner cartridge or this may release the paper so you can pull it out from inside of the printer.

Q. printer shows "Drum End Soon"

-
A. The message "Drum End Soon”, which indicates the drum unit need to be replaced soon. When the LCD or the status monitor displays the message "Drum End Soon”, you can still continue to print. You can replace the drum unit when you find the print quality is no longer acceptable or when the message "Replace Drum" is displayed. Please follow the instruction of OEM to replace the new drum.

Q. "Toner Low" message

-
A. The message "Toner Low" indicates that the toner cartridge is approaching the end of its expected life, but still has not reached its life end. It is recommended to continue printing if the printouts is still good. You should replace the toner cartridge when you find the print quality is no longer acceptable or when the message "Replace Toner" is displayed on the LCD.

Q. Why the color on the printouts is not exactly same as displayed on the computer screen?

-
A. Various monitor drivers will produce slightly different color scheme therefore the colors displayed on the computer screen will always slightly differ to the printouts. You could try to make an alignment, but be aware of each program uses slightly different driver so each color scheme would be in due cause.

Q. "Non-genuine cartridge is installed, continue?" message

-
A. Warning prompt is set by the printer manufacturer; just click YES. There is no impact to the printer and print quality.

Q. if you get poor print quality

-
A. firstly pls change another cartridge and try to print several pages. If the poor print quality is still there, it is most likely due to printer problem. If the problem goes away, in turn it is the cartridge problem.
