Re: Poor sound quality from Hi-Fi
It may have a ffew components in it that have failed, the only way to know is to have it checked by a technician. Call the nearest electronics service center to your home and ask them if they repair this brand. If they do not, you can ask them if they know who does in your area. Tell me where you are at and I may be able to find one for you. It does need troubleshooting to determain the cause of your problem.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

On my 901, I can reduce the size of the PDF file by changing the "quality" setting in the scan mode. More specifically, reducing the DPI that it scans at. I also noticed that scanning a document to a wireless network computer, and then scanning the same thing again directly to a flash drive plugged into the printer, results in significant variations of the file size. Perhaps trying different combinations of these things will help you with your problem. Good Luck.
sounds like your toner cartridge is faulty. Has it been clunking since you replaced it - if so have you bought a 3rd party toner - some can be really poor quality. id reccomend getting a hp cartridge or a decent 3rd party
This is adirect drive type and the poor picture quality has nothing to do with the belt.
The fault can be due to
1. fault head- since this is a Hi-Fi type , it is 6 head type. try cleaning the head to confirm, use a clean cassette.
2. Problems in the head amplifier circuit.
3. Check the RF connection to TV.
4. Clean the audio head and use a ordinary cassette to confirm the sound. Also try with a Hi Fi cassette.
An equaliser is, put simply, a more complex tone control, giving you the ability to cut or boost more specific frequencies than a tone knob, or bass & treble controls.
It comes in handy for tweaking the sound from your hi-fi to just the way you like it. But beware, as it can make your hi-fi produce sounds that are so bass or treble heavy, that you can damage your speakers if you're not careful.
Adding another compnent into the chain (like a graphic EQ) can add a little background noise but this Technics EQ is a pretty quiet one & you probably won't notice the noise apart from when there's no music playing & you've got the amp turned up high.
The "crackling" sound you describe sounds suspiciously like mis-tracking. That is: The result of the Hi-Fi heads (which are on the rotating video headwheel or drum) not exactly following the recorded tracks. Have you tried adjusting the tracking slightly? The reason this happens is that the Hi-Fi tracks are MUCH narrower than the thinnest video track (used for 6 hours per T120 tape). Tape stretches and shrinks as it ages. Video recorders wear with normal use in such a way that the tracking changes.
The problem is often worse with tapes recorded at the SLP (6 hour) speed because the servo cannot correct errors as fast when the tape is moving slowly (on some machines only). Tape quality also counts...and manufacturers change their formulations without public notice. All these things can lead to "archived" tapes being lost. Solution: Use the best quality tape you can afford, not the cheapest; record at the highest possible speed. Store the tape carefully. Never use a cheap "rewinder" because they can over-tighten the tape causing wrinkles, stretches, and
other kinds of damage.
