clean heads on new XH A1?
 
I think I read but can't find it now that you should clean the heads on a new camera right out of the box. Is this true?

Bill Pryor July 7th, 2008 03:18 PM

Yes. Definitely. 100% true. Use a head cleaning tape...but don't overuse it. Follow the directions exactly. Usually, that means put the camera in play mode and let the tape run for 10 seconds. NOT record mode.

Chris Hurd July 7th, 2008 03:25 PM

This goes for any new tape-based camcorder. Never rewind the cleaning tape; just discard it when it eventually reaches the end of the cassette. Ten seconds is the longest you'll want to run it.

Many thanks for the knowledge base.

I've never heard of this before. Cleaning the heads on a brand new camera out of the box? What is the reasoning behind doing this?

Bill, why should you not use the cleaning tape in record mode?

Bill Pryor July 7th, 2008 07:23 PM

Because the camera will try to record on something it can't record on and you could screw up the record heads.

Bill Busby July 7th, 2008 07:54 PM

If this "clean heads before first use" has any validity or reasoning why do manufacturers choose not to advise this sort of thing. I've never owned a camera that had such a written warning. Is this along the lines of the old "wet vs. dry" blah blah scenario where they also chose not to include some sort of addendum sheet with a new cam purchase?

Silly stuff :)

Bill Thesken July 7th, 2008 07:56 PM

I must have missed that step in the manual, thought I read the whole thing before turning the camera on. Will any brand work, or is there a super special one to use for the A1?
Hopefully I can just buy it at K-Mart or Sears. I've used my camera for 4 hours of tape, with about 7 hours of playback for editing. Today I noticed during a playback the image in one particular segment freezes for a couple of seconds before continuing.

Bill, you didn't miss it... it's not there. And yes, any name brand cleaner will do.

Bill Thesken July 7th, 2008 08:15 PM

This is off the subject, but have you ever had the tape during playback freeze a frame for a split second before continuing? Same place every time. Is this the proverbial 'drop out'?

...and after searching the forums it looks like this is a classic case of dropoutitis.

Anyone care to elaborate on WHY you should run a head-cleaning tape on a new camera? I've never heard of that before, and I've never seen it in a manual. If anything I've learned that you should only use a head cleaning tape very rarely when your camera is showing signs it needs a cleaning.

Why would a brand new camera need it's heads "cleaned"?

Well, Canon themselves say (PAL manual p.25)
Quote:

"Before you begin recording
Make a test recording to check if the camcorder operates correctly. If necessary clean the video heads [p 144] "

Also p 91:
"Playing back a tape
If the playback picture is distorted, clean the video heads using a Canon Video Head Cleaning Cassette or a commercially available digital head-cleaning cassette [p 144]"

and p144 itself:
When the message "HEADS DIRTY, USE CLEANING CASSETTE" appears, when the playback picture becomes distorted, or if, when playing back a tape in HD standard the picture and/or sound becomes stops momentarily (about 0.5 seconds) the video heads need to be cleaned.

To maintain the best picture quality, we recommend cleaning the video heads frequently with the Canon DVM-CL Digital Video Head Cleaning Cassette or a a commercially available dry cleaning cassette.

Tapes already recorded with dirty video heads may not play back correctly even when you clean the video heads.

Do not use wet type cleaning cassettes as this may damage the camcorder.

If the playback quality does not improve after cleaning the video heads it may indicate a malfunction. Consult a Canon Service Centre."
On the other hand, I know a well respected technician who would never let a head cleaning tape anywhere near a consumer camera let alone a prosumer or professional camcorder, on the grounds (haha) that you might as well use sandpaper on the heads. He is firmly of the belief that video heads should only be cleaned manually - using solvents - by someone both skilled and trained. Frivolous cleaning should be discouraged on the "if it ain't broke..." principle. He advocated a routine of planned manual cleaning on professional camcorders.

On his advice, I used several Sony camcorders for 6 and a half years (many hundreds of hours of filming and capturing) on the same brand of tape without cleaning the heads once.
This was SD DV not HD, so maybe that's a factor.

I'm still very nervous about using abrasive head cleaners.

Travis Cossel July 8th, 2008 12:59 AM

Colin, thanks for the response. I think I'm with you. I'd rather not start off my camera's career with some abrasive action on the heads.

Allan Black July 8th, 2008 02:02 AM

Guys, the Canon HV20 manual P92 says,

'To maintain the best picure quality we recommend using Canon (dry tapes).....and cleaning the heads frequently with a Canon xxxx cleaning cassette or a commercially available dry cleaning cassette. Do not use wet type cleaning cassettes as this may damage the camcorder'.

Most manufacturers recommend changing the DV heads and tape guides after 1000hrs record/play. That's one heck of a lot of tapes, I'd say you'd update the A1 before you run the heads out. So I play the cleaner for 10-15 seconds before every A1 shoot, I always use new DV tape.

I cleaned my A1 soon as I got it with a Panasonic (dry) cleaner tape and use Pana 83min MQ tapes. No dropouts till one day I changed tapes on a windy dusty airfield.

After many years running pro magnetic recorders, I'd never use a liquid and cloth or dry buds in a miniDV transport. Lint or cotton strands could easily get in the system.

Cheers.

That's what chamois swabs are made for :)

Bill Pryor July 8th, 2008 09:10 AM

Absolutely--use chamois swabs only if you do it manually. Back in the "old days" (ie., shooting Betacam with a BVW300) I was religious about manual head cleaning, pulling the side off the camera and doing it manually. In that camera the head life was only around 750 hours, and I always got at least the minimum. In talking with a Sony tech lining up my first head replacement, I asked about cleaning and he recommended using the cleaning tape for 5 seconds every 50 hours. I've been doing that ever since with a variety of cameras, including DVCAM and HDV. Properly used the cleaning tape doesn't harm the heads. But like anything else the key phrase there is "properly used."

While Canon never said in the manual to clean the heads when you get the camera out of the box, it's been common knowledge on this board for a long time. Do a search and you'll see lots of posts about it.
