MPC307 - Energy saving, sleep mode, STR mode

[lukasha]

Hello,

I think my printer is not entering full energy saving mode. I conclude this from the fact that:
- increased energy consumption
- SP8-961-002 - not increasing
- Energy Saving LED - on (not blinking)
- ecolog:

I tried [Energy Saving Recvry. for Business Applicatn] - on and off. I have the sleep mode timer set to 1 min.

I would like to know:
- what conditions must be met for the printer to enter STR mode (I know about SP5191-01 - I have it set to 1)?
- what could cause such frequent change of power states?
- how much energy should the MCP307 printer draw in the saving state (with the Ethernet cable connected)?
- other ideas, suggestions??

Thanks in advance for your help.

try to check from user tools "fuser shutdown mode"
update the firmware.
if you have this suspicion, try to connect to the power plug one of those consumption meters that they sell in supermarkets or hardware stores for a few euros (procedure also suggested in the SM)

take a look here with the translator, I hope it can be useful to you

Verifica del tempo di attività per ogni stato di risparmio energia
Il tempo di attività per ogni stato di alimentazione della macchina può essere controllato con SP8-961 (Stato

SP8-941 da
006 a 009
Tempo di inattività Periodo cumulativo in cui il dispositivo è disabilitato perché il dispositivo
stesso o i suoi componenti sono nel seguente stato.
• SP8-941-006: SC (SC modalità di esclusione)
• SP8-941-007: Inceppamento (plotter)
• SP8-941-009: Fine alimentazione/Unità PM
Sulla base di questi di dati e dei valori dei consumi riportati nelle specifiche tecniche è possibile stimare l'energia
consumata dalla macchina.
Si tratta di un valore di riferimento, perché i consumi riportati nelle specifiche tecniche sono stati misurati in
ambiente controllato con alimentazione elettrica costante.
Per effettuare una misurazione esatta della sede del cliente, utilizzare un wattmetro misurando l'effettiva energia
consumata.
Utilizzare SP8941 per calcolare il consumo energetico:
• All'inizio del periodo di misurazione, leggere i valori da SP8-941-001 a SP8-941-005.
• Al termine del periodo di misurazione, leggere nuovamente i valori da SP8-941-001 a SP8-941-005.
• Individuare quanto tempo è trascorso nelle singole modalità (sottraendo la prima misura dall'ultima).
• Moltiplicare il valore trovato per il consumo specificato per le singole modalità.

• Convertire il risultato in kWh (kilowattora)
Raccomandazione
Si consiglia di salvare le impostazioni di default relative al risparmio energia.
• Se il cliente desidera cambiare queste impostazioni, è necessario spiegare che i costi energetici possono
aumentare e che l'aumento del consumo energetico danneggia l'ambiente.

Thank you for your answer.
The firmware is up to date.
I also tested [Fusing Unit Off Mode (Energy Saving) On/Off] - unfortunately the printer does not enter STR, and in the logs you can see that it enters and exits various power states.
I also looked through all the SPs you write about, that's how I know that - SP8961-002 - does not grow.
Power consumption - around 10W seems like a lot, the manual says that in sleep mode <1W (although it probably doesn't take into account the network). It's not even about power consumption, but why the printer behaves like this (changing power modes), is it normal?

if possible, try to leave disconnect the lan cable for a neccessary time to determinate if he receive a some kind of signal that causes this behavior

Ok, I'll try and come back with information.

Youmay have frequent status queries being sent to the C307. This will cause the print engine to come out of sleep mode but will leave the display off. Fusing unit will warm up to standby preparing to print a job. That would explain the increased power consumption.

I quickly (2h) ran a test - power consumption dropped very slightly - maybe 0.5W - I will repeat the test and review the logs.

I think there might be something to it. I'll do a test without a network cable - then everything will be clear - I'll come back with news.


I'm attaching the latest log - interestingly, you can see that the printer woke up at 1:00 (maybe some device polled it). I'll run tests without the network cable and let you know.

However, even though nothing woke the printer up for many hours, it still didn't enter STR mode (8961-002 confirms this). Do any conditions have to be met for the printer to enter STR mode?

Currently the printer does not have a network cable - I will check in a while.
In the meantime I got a second printer MPC307 and the power consumption is similar - 9W in sleep mode. So it is normal.

However, I noticed that both printers make a strange sound in standby mode - a quiet squeak, maybe the coils? Is this normal in these devices?

I never noticed it, maybe some fan(?)...anyway the EU version is at 0.81w on the SM.
if you compared it with another machine, 10w seems like an acceptable value to me...you should leave it like that, otherwise you'll get a big headache

That's why I'm giving up, since both have the same thing, it's OK. Thank you very much for your help and commitment - I learn a lot from you.

I think that nothing can be done about this sound without replacing the power supply. The sound is only in sleep mode (9W of current use), all fans are off, most likely the noise comes from one of the transformers. Here's a link to a YT video showing the problem:

seem a noise of high frequency trasformer, maybe perhaps the insulating paint of some coil not glued well that vibrates at high frequency(?)

[lukasha]

I tried touching the coils, transformers (of course with an insulated stick) the sound did not change. With a sound meter I came to the conclusion that the noise comes from the transformer at the bottom (most likely because it was difficult to determine it clearly) - what you can see in the video. I searched the internet for this transformer, unfortunately I did not find it.

I guess I'll have to get used to it :/

To me having a transformer "sing" is not uncommon. It has to do with the laminated steel plates that make up the body of the transformer. It is nearly impossible to prevent them from vibrating. Same thing with motors. Often if you try to replace you end up with one that is louder.

In the old days of CRT based TVs and monitors the horizontal oscillator coil ran at a frequency just above the human normal hearing range. But if it was extremely loud some people, myself included, could sense them.

You're right. From now on I'll consider it normal. Thanks for the explanation.

I have a transformer from an external HDD, which for years if you get close, you can hear a strange noise like a flying saucer from black and white movies from the 50s..lol
