which old printer to choose

[Artsem]

1. you said that envy 100 (i'm going to buy 110 actually) has automatic printing on both sides of the sheet:

2. I heard that the printer needs to be turned on periodically.

When turned on, the writing head self-cleans.

How often should the printer be turned on? Once a month? Or twice a month?

I would like to turn it on as rarely as possible.

Hi @Artsem 

For inkjet printers, it's recommended to turn them on at least once a week to prevent the ink from drying out and clogging the print heads. I'd recommend the Envy 120. But ultimately, it's up to you to choose the model you like best and best meets your needs.

I hope the above is helpful!

1. I understand that 120 is better, but it is not so easy to find it today.

Please answer the first point above.

I want to know what I'm missing out on if I buy the 110 (other than speed, AirPrint, touch screen size, and ease of paper feeding).

2. What voltage does this printer require for power?

The printer that was sold in my region.

You did provide some tables. Is it indicated there?

Thank you

Hi Artsem

To check more thoroughly you can check more specifications and manuals from:

HP ENVY 110 e-All-in-One Printer series - D411 

I hope the above is helpful

You gave a guide for 110. Don't I also need a guide for 120?

Hi

I provided you with the previous guide because I stated that I was going to purchase the HP ENVY100 printer. I also leave you the link for the HP ENVY120 so you can learn more about them.

I hope the above is helpful. If I've answered your questions, I'd appreciate it if you could mark the post as solved.

you said that I should turn off (I heard that it should be done with a button) and turn on the printer once a week, because this automatically cleans the writing head.

question. can I use a time relay for this?

a time relay is a microcircuit that supplies electricity to the printer for a short time.

it's the same as if I plugged the plug into the socket for a minute, and then pulled the plug out of the socket.

will the writing head self-clean in this case? or do I need to press some buttons, for example, when turning it off?

thanks

Hi Artsem

I'm glad you remembered the suggestion to turn your printer off and on weekly to help keep the print head clean.

However, using a time relay in the way you describe, where it just interrupts and restores power, likely won't trigger the automatic print head cleaning cycle on most printers.

Why a Time Relay Won't Work

Printers are designed to perform a print head cleaning cycle when they are initiated in a specific way, usually by pressing the power button directly on the printer's panel. This process involves the printer:

• Recognizing an intentional shutdown signal: The printer registers that it has been given an "off" command.
• Completing a proper shutdown cycle: This might include saving settings or moving the print head to a "rest" position to protect it.
• Recognizing an intentional power-on signal: When you power it back on with the button, the printer runs its startup routine, which often includes a small ink purge or cleaning cycle to ensure the nozzles are clear and ready to print.

A time relay, by simply cutting and restoring electricity, is more analogous to a power outage or abruptly unplugging the power cord. In this scenario, the printer doesn't have the opportunity to execute its programmed shutdown and startup routines that include the print head cleaning cycle. In some cases, it could even be detrimental to the printer if power is cut abruptly too often.

What You Need to Do

To ensure the print head is automatically cleaned, you must turn the printer on and off using the power button located on the printer itself. This guarantees that the printer completes its internal processes and, upon powering on, performs the automatic print head cleaning.

I hope this clarification helps!
