Answer from Alisa Kiryanova[guru]
this is the control panel of this plotter
It has 3 types of print head cleaning:
for soft cleaning: With the plotter turned off, press the Power button while holding it 2 times, press the Cancel button
For Medium: Same thing, just press the Continue Button one more time (it's number 3 in the photo)
For heavy cleaning: Same as for soft cleaning, only press the Continue button 2 times
cleaning should be done from soft to heavy and no more than 1 for each ... so as not to damage the oven. head
There is also an instruction, but it is in English:
Answer from Bruho[guru]
You take out the cartridge and calmly wipe the printing side with a paper towel. If the paint is dry it will help. If it's over, then no. And then I started and ended with this ... throwing the printer into a landfill. Something went wrong with the electronics. parts were not found. repairs are more expensive than new.
Answer from Anton Klopov[newbie]
By the way, we also have a plotter - so I'm wondering - what is the best way - so that it is constantly turned on or every time tuij turn it on again and do the cleaning ???
Answer from Boris Batchaev[active]
Inkjet printers MUST operate continuously.
From the nuances:
checked paint (if not original), spare heads, constant temperature and humidity in the room, no drafts, wet cleaning 1-2 times a day, no dust, power stabilizer (preferably Smart UPS), paper with low dusting (again, if not recommended by HP).
If there is a CISS - once a year, a complete flushing of the ink supply system with special solutions.
And don't forget to shake the cans...

The HP Envy 110 MFP is a slim, compact, yet stylish and well-designed MFP. Envy 110 Has a high resolution screen, WiFi, duplex printing. In Complace we carry out repair of HP Envy 110 at low prices, we fix most of the breakdowns.
What we do:
- scanner repair - 2000 rubles.
- screen control repair - 2500 rubles.
- we fix problems with a retractable tray - 2500 rubles.
- carriage jamming -2500 rub.
- power supply repair -1500 rubles.
- restoration of print quality - from 400 rubles.
Let's look at typical Envy 110 malfunctions and show you how to disassemble the device.
Screen control repair
Due to its thinness, the touch screen lifts up when printing to make room for the paper to exit. It is not uncommon for the HP Envy 110 to have a broken screen-raising mechanism. Instead of a smooth rise, the screen twitches and freezes half way. “Screen Error” appears on the screen because the printer is no longer working.
The HP Envy 110 Motor Module consists of the motor itself, an encoder, a board, and a cable. Repair of the HP Envy 110 screen position control mechanism consists in replacing one of the motor modules. After replacement, the screen opens and closes.
Drawer Control Repair
The HP Envy 110 printer starts moving the screen and drawer as soon as it is turned on. If the paper drawer is not working properly, such as jerking, the printer will not print. Moreover, the tray cannot be removed - without it, the printer will also not work. Primarily due to the fact that the tray switches the sensor flag.
A problem with the tray is possible, firstly, due to a breakdown of the engine, and secondly, due to a malfunction of the motherboard.
The drawer control motor is located under the board on the right.
We change the entire structure along with the encoder.
HP Envy 110 carriage jam
The HP Envy 110 received for repair had a malfunction: a few seconds after turning on, the carriage stops and the message “the carriage cannot move, the carriage is stuck, remove the obstacle ...” Cleaning the encoders did not help. The cleaning of the parking lot did not help either. The culprit for the carriage jamming was a faulty carriage motor.
As a replacement, the carriage motor was taken from the HP Deskjet Advantage 5525 MFP.
The message "carriage jam" means a lot of problems with incorrect positioning of the carriage. For example, when there is no speed feedback from the encoder strip. The sensor on the carriage and the control board are responsible for processing this signal with a clean tape. If the sensor works, then the cause is a faulty main control board. 
Repair in this case is most likely impossible.
HP envy 110 won't turn on
If the HP envy 110 MFP does not turn on when you press the power button, there is a problem with the main control board or power supply.
A specific example with a burned out HP envy 110 power supply: The MFP did not respond to the power button, although the power indicator was blinking.
In the HP envy 110, the power supply is made as a separate device, which is located inside the case on the left side. The Envy 110 power supply has 2 supply voltages: 32V and 24V. The body of the block is glued, so it is very inconvenient to disassemble. 
After opening the case, we find a typical switching power supply circuit. 
In our particular case, an electrolytic capacitor exploded in the primary circuit of 120 uF at 400V. Moreover, the electrolyte flooded the entire circuit and burned 2 more capacitors.
After a thorough cleaning and replacement of the capacitors, the power supply worked. The MFP began to turn on, but hung at the initialization stage. To return the MFP to working capacity, it was necessary to reset the control board.
HP Envy 110 disassembly
First, remove the side covers, which are attached to the latches.
Raise the scanner and remove the top cover covering the main board.
Then remove the top caps.
On the right are 2 engine modules. One raises the screen, the second extends the paper bin.
To get to the modules, you need to remove the main board.
The hardest part is removing the scanner. To do this, disconnect the cables, press the latch of the lift bracket (the place is shown by the arrow), move it inside the scanner, release the bracket on the right and left, remove the scanner.
We unscrew all the screws securing the top cover from above and remove the cover.
The circle indicates the carriage motor that we will be replacing.
When disassembling the carriage, we check the carriage position sensor using the encoder marks, the microcircuit for reading and controlling the signals of the cartridges.
This MFP was bought by me a few years ago realized. I settled on this model because of the possibility of refilling cartridges. I specially purchased a set of refillable HP178 cartridges (bought), as well as an OCP ink set (bought). The overall impression of the HP B110B MFP is excellent. BUT!!! I don’t know how ordinary users use it, I have constant problems with repairs. Once I even turned to the workshop - they said to throw it away. I've been throwing it out for about a year now. Super masters do not want to work even for money.
The main breakdowns in the HP B110B MFP are the loss of contacts in the carriage loops and broken contacts at the cartridge installation sites. The cost of printing is a penny. Print quality is excellent even with cheap inks. I tried to buy a new MFP several times, but ......
The first repair was to replace the print head. I did not find a head in Russia and ordered from China. Who needs a head press HERE. Installing the head was also dancing with a tambourine. Bottom line: it still works and most likely the old head was also good, but the problem is in the trains on the carriage.
I tell you how to quickly disassemble the HP B110B MFP.
Reason for disassembly: HP B110B MFP DOES NOT SEE BLACK CARTRIDGE.
Raise the lid of the HP B110B MFP, the head is parked in the open lid position.
We unscrew 6 screws and here is the first surprise. Two screws cannot be unscrewed just like that - the cover of the SCANNER UNIT interferes.
The side covers, in addition to the screws, sit on 3 more latches on the bottom of the printer.
On the left side, after removing the cover, disconnect 2 cables white and black.
On the right side, unscrew the screw securing the limiter.
Lifting up, remove the scanner and put it aside. We don't need it yet.
Now we have access to 2 problematic screws. We twist them and remove the cover.
This is what the HP B110B MFP looks like from above. The head, carriage and cartridges are already available to us.
If the problem is in the loops, then we already have access to them. Repeatedly I inserted these loops back, and after some time of work they again departed.
If the problem is not in the cables, then we continue to analyze the HP B110B MFP. We remove the cartridges. We don't leave them open for long. I don’t use lids, because I work on disassembly with my eyes closed and they don’t have time to dry out for me. The same goes for the head.
If you remove the head cable, then keep in mind that there is a movable silicone stop under the cable. I forgot to take a picture of it.
To remove the carriage, loosen the toothed belt tensioner.
Remove the left and right cotter pins securing the carriage shaft.
Remove the shaft by pulling it to the right.
Now we can raise the carriage. Complete freedom of action.
Checking the ink cartridges
We disassemble the carriage. To do this, release the head holder - remove 2 springs.
Remove the cover covering the board. It has 2 latches and is easily pry off with a screwdriver.
We unscrew 1 screw securing the printed circuit board. And we charge.
We study the board for micro cracks
Now remove the cartridge contact board. There are a total of 6 latches, 3 on each side. The plate is spring, keep this in mind.
We get access to the cartridge contact board. In my case, the reason is precisely in this board. We clean contacts
Check moving contacts. They are easily interchangeable.
Assembly is carried out in the reverse order. The disadvantage in this assembly is that the cables are not fixed in any way. Thus, they bring unnecessary trouble to the owner of the HP B110B MFP.
This assembly - disassembly helps even if various ink system failure errors pop up:
0x19a0013
0x19a0003
0xc19a0020 and so on.
The whole trouble is in the loops !!!
