An exclamation point in the triangle is lit on the printer.

The lights that are located on the control panel indicate a specific condition of the printing equipment. The lights may be on all the time, turned off, or lit according to the status of the printer. Flashing indicates the status of the equipment or possible errors in operation.

Triangle exclamation mark on printer

In certain cases, users do not know why the triangle on the printer caught fire or blinking. Most often this problem occurs during the operation of laser equipment and in order to solve it sometimes you only need to know some basic reasons.

The indicators on the panel are needed to indicate faults at specific nodes. Light bulbs can respond to various changes in equipment in various ways. For example, indicators may blink or light for a long time. Sometimes indicators do not show any signs of "alarm".

Flashing

If during operation the MFP stopped working and a triangle began to flash or the letter P probably appeared on the screen, then first you need to disconnect the device from the mains. After that, carefully remove the cartridge and inspect the printer for a paper jam.

If particles of paper have been identified, and probably a complete sheet, you need to carefully remove it. It is necessary to pull out very carefully, since the device has different sensors that can be broken. After visual inspection, restart the printer. An exclamation mark with a zipper in the yellow triangle may also flash.

Is on

Most often, the main reason is the chip that is on the ink cartridge, which must be replaced with a new one during refueling.

Reference! For this reason, it is recommended to refuel at repair shops. If this condition has not been met, then the red triangle or the letter P may light up on the display, this indicates a malfunctioning cartridge.

How to fix the problem

Main malfunctions and solutions:

1. If a red lamp on a Hewlett Packard device indicates a “Warning” (in Canon models, an exclamation mark lights up in this case), it may be that there is no print cartridge in the printer. To fix this error, you only need to open the housing cover, gaining access to the connector, which is necessary for consumables. Then, remove the protective film from the newly installed cartridge and reinsert it into the opening until a click is heard.
2. If both lights on the panel light up, that is, red and green, at the same time, then the device initializes.
3. If the green light flashes, then for printing the equipment processes the data or receives it.
4. Sometimes it happens that the green button starts to light up all the time, and the red button flashes only occasionally - this is a general error in the printing equipment or a malfunction in the paper feed. This is most often accompanied by jams.
5. If a red button illuminates from time to time on the panel, this indicates that the cartridge is not inserted correctly. Moreover, such a signal may appear when the housing cover has not been completely closed. To fix this problem, you need to remove the cartridge and insert it back into the slot.
6. If the red button in the Hewlett Packard models starts flashing, then this may be as a result of an incompletely removed tape. To remove it from the printing equipment, you will need to open the housing cover. In addition, packing tape must be removed from the trays.
7. If both bulbs on the printing device light up all the time, then this sometimes indicates some serious problem, which most likely will not work out on its own.
8. It should be noted that for Canon models, a triangle is responsible for determining the trouble code. Accordingly, if this symbol lights up on the printing equipment, then you need to write down the code displayed on the device’s screen, then read what it means in the equipment manual.
9. At the same time, for Epson printing models, instead of two bulbs, a drop lights up during the presence of an error. For example, if it blinks when the cartridge is fully refilled, then to fix this problem you need to reset the ink counter using some kind of service software, for example, Print Help.

Reference! That is, indicators on the printing equipment report the presence of certain problems. Most of the faults can be fixed by yourself, even if there is no specific experience.

If any of the buttons on the printer starts to burn, then first of all you need to familiarize yourself with the operating instructions. But in cases where the cause of the malfunction is not precisely determined, it is advisable to contact the repair shop, in which the printing device can be examined for the presence of certain malfunctions.
